I bought a Wilson Sleek when they were changing names, right before the price went up. I think they are a couple hundred now so I'm not sure I would still go that route. I typically get 2 - 3 extra bars signal strength in the mountains and I just run the small magnetic mount antenna that came with it. There are a few times I've only gotten 1 extra bar, and I can't tell you what the difference was. It does take a few minutes it seems for the phone to recognize a better signal once I put it in the cradle. For me it does what I need it to do, which is get a message or phone call out in marginal areas, so it was worth the roughly $100 I paid for it. I'm not sure if I'd pay $180 for it and that is what the Weboost lists for on Amazon right now - it looks to be the same as the sleek. For those who really need a strong signal for videos etc, I hear that a directional antenna does make a big difference. Just not worth the extra money and hassle of set up for me.
