I got a kick out of the euphemisms used in their marketing literature. "A red line appears on the material that lets you know that the cartridge has about two more flushes and you should change the cartridge. If you ignore the indicator, the material will run out in the next flush or two, and the top edge of the material will be visible."

Top edge of the material. Great way of saying mountain of poo.

Looks like a lot of plastic that gets thrown out with each bag change. There's a whole collar and everything that gets disposed of along with two bags. I dunno, if I have to bag it I go for a single bag at the time and be done with it...

I can see where this item fills a market niche though.
 
My 2 main questions would be amps during operation and cost of replacement cartridges.

"Poop burners" are used sometimes on boats and other off grid applications.
 
I went to the web site and after a few minutes I just called the company for a price,  it's  $595.  This seems to be in the price range of some  other portable off grid "waste" disposable units. I like their concept however IMO at the end of the day it's still  a plastic container that uses plastic bags and needs to be emptied when full. 

 If/when I am ever able to live off grid & on wheels I will then, as now have to prioritize any spending outside of regular monthly costs.  $595 for me would go a long way in a "get out of Dodge" fund.   I  think even if I had the funds available I'd go with plastic bucket,lined with plastic bags, saw dust between "deposits, Lugable Loo seat. This is what I think now, as life conditions change my needs/wants may have to be adjusted.

As my dearly deceased husband often said "It's good if you like it".   That's my story an' I'm sticking to it and Queenie sez ruff ruff! :)        Texas jbird

It runs off its own battery.  The cartridges average out to a result of it costing about 1$ per flush.   

I'm more curious if it actually seals up the scent or not; they say it does 100% but I'm skeptical.

I can certainly see that being an attractive option. One thing I've always disliked about 5-gal buckets is the need to deal with disposal on such a regular basis...if this lets you put it off to even weekly or longer with not more thought than pressing a button, I might be interested.

I surfed their website and watched some vids, but the FAQs seemed to be lacking some basic info. One, how many "flushes" is in a cartridge and does deposit amount (aka poo pounds) effect that? 

Two, does the flush actually create a seal, or is it just a twisty motion?  And what exactly is all that vacuum action accomplishing?

I hope you post back with your experiences.
 
Yes, it has it's own battery, but it will need to be recharged or hard wired. Solar users are concerned with amp usage either way.

I think I would prefer a tray type. Remove tray, dump ashes (once a week), replace tray...done deal.
 
Reading through some reviews, I found many positive ones even though everyone acknowledges it's expensive. Here is one unhappy customer who's experiences seem to cover what the negative reviews have to say:

This quote was taken straight from their website:
“As the waste bagging system is isolated in an airtight compartment, there is no odor or spillage.”
I wish it was as easy as it sounds…
I was so excited about this product and quickly embraced the concept . I bought one for my RV that I planned to live in full time. I thought that it would be easier and cleaner than dealing with a septic tank. Boy was I wrong.
I am having some major issues with my Dry Flush.
1. First I had no idea that the expense was going to be so high. The refills are minimally $50 each. Initially I thought that I could get two uses per flush to cut costs. Wrong again.
First - if you do that then when the unit does it’s magic spin thing the fluid does not get fully contained and comes up through the top. Often even a second flushing does not remedy the situation.
Secondly - and finding out “the hard way” the bag becomes astronomically heavy. I could not lift it and had to enlist help. How embarrassing.
2. Giving up on the idea that I could get two uses per flush, I began flushing with each use… and still had problems with the unit not wrapping the entire amount of fluid. I had just replaced the cartridge and I had to flush up to 3 times to wrap all the fluid.
Leading to another problem… no longer odor free.
As the cartridge gets fuller the problem gets worse and I have had urine collect on the inside part of the unit. Yuck.
And it is still much heavier than I ever imagined. I am a woman alone with a bad back and a torn rotator cuff, I had no idea I was going to have such a hard time with this.
3. The video instructions state that when you get to the red line you have one flush left. I have not found that to be the case either… you get to the red line and you are done. You’d better just flush it dry right then and there or more of the same as above - overflow. Not fun.
I am really disappointed. I was so excited about it initially and it just is not working as advertised. I am sorry I removed my old unit.
The cost to use the DryFlush is going to be way more than I initially thought, I knew it would not be cheap - but I was not prepared for multiple flushings per use. I was also not prepared for the weight of the used bag, or the odor.
***Update***
This morning, after the most recent cartridge was inserted, I only got 3-4 uses out of it and when I flushed, it totally overflowed. It’s a disaster. I can no longer use the toilet at all, since I now live full time in my RV this creates a real problem. I have a nasty mess to clean up, again… I had ordered 6 more refills, not yet received, but will be sending those back.
I tried to return the unit to Home Depot, they stated that since it had been installed and used it was now a “biohazard” and could not be returned. They said I would have to contact the company directly. Oh fun.
I contacted the company via their website and an email. No response. I called and was told they would open the emails and get back to me.
When they finally emailed me back they said there was nothing they could or would do. They claimed that since I bought the unit over six months ago it was out of warranty. So now I ask - I used it for two overnight vacations and began living in my RV full time April 1, 2016. By April 11 it is not functioning as promised and they refuse to take it back. Most vacationers do not use their RVs so frequently so the problem may not show up as quickly as it did for me. Is a 6 month warranty really adequate for a piece of vacation equipment this pricey? I was extremely disappointed with the customer service, no empathy, not willing to do one thing to even attempt to make this right. All they told me was that I could send the unit back to them, at my own expense, and they would look at it/repair it, again at my expense.
I am not happy with how the company handles issues and their product does not perform as shown on their videos and stated on their website. It’s not a cheap product to buy or to use, their attitude towards purchasers sucks.
 
Wow very sad that someone lost so much money just to find out the thing wouldnt work for them... or very well at all for that matter.

Even if it did work right, 595.00 is a heck of a lot of trash bags ... and thats not even including the cost of the $50.00 cartridges :p TBNT!!
 
If you're going to spend that amount of money then I seriously recommend going to a C-Head instead of the DryFlush.

Same initial investment, much cheaper to operate (a block of pine shavings once every few weeks from W/M) and no batteries to be recharged.

Yes, you still have to empty containers but dumping a one gallon jug of urine every few days depending on # of users and emptying the solids container once every few weeks (again depending on usage) is really no big deal. I empty the solids more frequently than most probably would so that the pail doesn't become too heavy for me to manage.

No chemicals, no odors at all, no dump stations, no batteries, low cost operation.

At least 2 of us here are using the C-Head with great success and satisfaction.

I saw that review and I did find it troubling... but at the same time her vagueness about what happened gives me doubt.  I've tested the toilet many times with bottles of water and I don't see how what she described could possibly happen, especially in her last quote which I excerpted above.  What does she mean "it totally overflowed." ?

When you flush, the cavity containing the waste first inflates to surround the waste, then is sucked and twisted down multiple times.  Indeed, as another 'moderate' review of the unit said, the inflation part is slightly dangerous because with liquid (not solid waste mind you!), droplets get pushed up to close to the rim of the seat before they're sucked down, and sometimes it takes a second flush to get them all down.  His solution was to coat the bag cavity with toilet paper before urinating so it would have weight and wouldn't get pushed up at all.  I think that would have solved this woman's problems, and is what I plan on doing.  The other possibility is that too much waste gets piled up underneath towards the end of a cycle, which would make the inflation more dangerous because it would go even higher since it's starting from a higher point.  Perhaps this woman was particularly large or emptied a lot of waste into the unit in her final disaster.  

Regardless, she is right that DryFlush should have solved this problem and should have helped her.  

I'll get back to the forum after I actually use it so it's not theoretical anymore.  I actually got the unit more in the interests of guests in my truck than for me... I realize it's first-world wimpyness but most people can't tolerate bagging their waste by hand.
 
Seems like the price range of a composting commode, with a lot more costs and landfill waste.
 
FIRST REPORT:

Used it for two weekends in the desert 95+ degrees. I went number 2 in it a week ago and it's been sitting in my truck in that heat... I stuck my face into the toilet boil and smelled pretty hard and didn't smell anything. Disgusting I know, but it must be reported for the greater good of CRVL.

I'm going to install a rubber seal under the seat and cover today and put a latch on it so it seals tight... honestly I don't understand why they don't sell it like that, it would seal the odors in even better and keep shower water out, which is important because my bathroom is wet.

I've also been able to see how the unit works in more detail... basically it's just an electric bag twister, and the metallic bag that receives waste sits in a black trash bag which ensures there's no spillage into the main cavity of the unit. The basket the black bag sits in twists.

As far as I can tell at the moment, there's no way that woman who gave that bad review of this unit could have had such a bad experience unless she was really mechanically unsavvy. It is literally impossible for liquid to spill up and out of the metallic bag, unless she somehow punctured it or was installing it completely wrong. Maybe I'm missing something that will be revealed later but the unit isn't complicated, and I can't fathom how it could mechanically fail.
 
As a slightly older woman...who are they kidding with 17 uses being a weeks worth?? This is not a separating unit...

This was designed by a man with men in mind by the looks of it as it doesn't seem suitable for urine disposal at all.

I don't doubt for one second this woman's review story nor do I think her inept. She specifically said the liquid was a problem & no doubt!! Seriously...trying to gizmo wrap a bag of pee? Or an issue men don't (usually) face when nature calls for both urine & faeces disposal at the same time?? Cuz that sh¡t happens...

The C-Head looks decent enough but I am using the guts from a Nature's Head in a custom box when I redo the toilet as it comes out a bit cheaper & I have access to a (omg to die for!) workshop over winter in Quartzsite.

One aside here, I dumped the solids from my composting toilet in a couple places up here in the hills last year, just once in each spot. I checked this spring & there was not one trace of the coconut coir or anything. I wouldn't do this on a regular basis, just wondered what a few months in open nature would do to it...it dealt with it.

It's not a sexist unit, my girlfriend was with me and it worked fine for her  ;)

I re-read the woman's story and I think I know what her problem was- she wasn't getting the battery charged fully enough.  The unit will do lousy half-flushes if it's not charged... but again, it's really obvious that it's not a full flush.  Either that or it wasn't twisting enough times around her liquid due to an intrinsic mechanical error, which again, is very obvious.  Look at the picture below, note that the metallic bag is sealed up into the black lip, so it's physically impossible for liquid to get up over that into the main cavity of the unit.

Either she was upset about the unrelated negatives of the unit and made up the story, or she was missing some really obvious cues.  

All of you can be sure, if the unit fails for me I will give a very specific reason why so we aren't left analyzing some vague story several years later lol.
 
SECOND REPORT:

1 & 2 at the same time not advised, unless one places paper towel down first- the initial inflation of the flush could easily push undesirable matter onto the white under-rim of the toilet (though not the seat).

Still smells ok, defecation has been in it for 3 weeks in the sun now.

All else is fine... at least with the toilet side of my life
 
What does what's in the toilet have to do with function? That is to say, why are they ok seperate but not together?

During the initial part of the flush, before the bag starts twisting down, it sort of pushes up like a jiffy pop (you can see in video).  It's the only dangerous part of the toilet because if liquid matter is in there, it can push up and touch the side of the seat rim.  Solid matter is fine because it's too heavy to get pushed up.  That's why many reviewers say to put down a paper towel before you go 1 so the liquid stays down.

It looks like a larger, toilet-shaped version of a diaper genie or cat litter genie.  They basically have a super long continuous internal bag that twists between "deposits."  Before the introduction of the litter genie, I was using the diaper genie for disposing cat litter, and found it to truly be odorless, although a bit poorly designed for cat litter.
