I have the fluid 2 (first gen, with knob instead of yellow lever). I hate it and it returns the favor with torture.
I haven't had the leak issues as some have reported on the earlier models, and I have roughly 200-250 hours on it (over the course of 5 years). It takes time to warm up, where it will then give a very good resistance. It's pretty quiet, but my rollers are acutally a little quieter.
I prefer the rollers indoors, but when I want to hit targets the fluid 2 is easier to get there and stay there.
