I just ordered a KK road machine fluid. I've tried out a mag resistance trainer, and it was too loud for my needs. I coach swimming every afternoon, and it is dark by the time I get home - especially after the time change. The only time I can get a ride in is on a trainer between 5:00 and 5:45 every day while my wife and kids are sleeping. From everything I have read, it is much more quiet than the others, so I hope it works out for me.
