I have the Cycleops Fluid 2 and have been very happy with it. I have had it for so long I can't remember not having it. The resistance unit did start to leak after a few years, but I sent it in and they covered it under the warranty - sent me a brand new resistance unit of their most recent model; so it was almost like getting a whole new trainer. The new unit has been going strong for several years now.
