Another cycle-ops fluid trainer user here. I have used mine for 3 years in the winter time without a problem. I did hear that some made a few years ago did have a leaking problem, but cycle-ops has since addressed that issue and I have not heard of people having problems since. As of last year, my husband got one as did my girlfriend and we get together in my living room twice a week to train with a dvd. In between I have no problem getting on the other days on my own by just watching tv although nothing beats the fresh air by riding outdoors.
