I have a Performance TravelTrack fluid trainer that's about 6 years old. Bought it after I had knee surgery , put away after it healed and just pulled out of the garage a few weeks ago after surgery on my collarbone.
I just rode it for 3 hours today.
It doesn't have adjustable resistance, but I can change gears if needed, I almost always keep my bike in the highest gear.
I rode it allot back when I first bought it and it's worked flawlessly now after being unused for 6 years. The new one looks a lot like mine. Mine has a different engagement mechanism and a small flywheel. I'm very happy with it and I'll be using it a lot until my MD says I can ride on the road again. It doesn't tear up the tire or make a lot of noise.
It's a great unit I highly recommend it.
I have the Cycleops Fluid 2, and I would recommend it over the Travel Trac. I don't know anything about the Travel Trac, but it looks puny (frame and fluid unit). It looked like they don't give you a video with the puny one either.
I think the Fluid 2 will take like 700 watts or something... you won't max it out.
