I'm just going to say what Ryobi has been for me, AWESOME. I purchased a multi piece kit close to 20 years ago that included a Flash light, Skill saw, Drill motor and Saw's all using 18 Volt Nicad batteries and a charger in a single large case. Everyone of those tools is still working as good as the day i bought them and I have used the ever living crap out of them. I did purchase over the years replacement batteries and last year I decided to replace them with lithium Ion batteries and a charger. It was no surprise to me as I have been using Lipo batteries for years in model airplanes that the batteries for these tools work incredibly well.
I recently needed a router and choose Ryobi again, compared to many others it works very well at a lower cost.
To each his own, I am happy with Ryobi!
