I like them alot. Quality is high. Set-up seemed easier than with a standard trainer with the one we used. And there's no wear and tear on your rear wheel/tire like in a standard trainer. The drawback for me was that it's a wind trainer which means it's pretty loud.
My vote for best trainers goes to either the Cyclops Fluid 2 (which I have), or their magnetic trainer. Both are quiet and will take as much power as any mortal can put out. I actually much prefer using rollers over the stationary trainer.
I don't have a lot of experience with vampires, but I have hunted werewolves. I shot one once, but by the time I got to it, it had turned back into my neighbor's dog.
I have a cycleops fluid trainer. Don't know if it is a #1 or #2. It works fine, but you don't get
any objective feedback of your ride like miles, watts, etc.
