I wouldn't be without it.

As long as you have a reasonably stable bench to mount it on you should be fine. I doubt that you could get anything else as good for the money, and it's the same clamp as used on some of the full size stands.
To use it, you'll need about 4" minimum of tube to clamp to, as that's the length of the clamp itself. Usually this means that the seat will need to be high enough to provide at least 4" of seat pillar to clamp to, if you don't want to have to adjust the seat height each time. Alternatively you may find somewhere else to clamp, as long as you're careful that you choose somewhere strong enough.
To avoid the pedals hitting the bench each time they turn, in my case I fitted the edge of the clamp level with the edge of the bench to give maximum pedal clearance, and it works really well for me.
Also, I find that it's best to leave the front wheel touching the ground, which prevents too much load on the clamp. If you don't have the front wheel on the ground, I think that unless you have a very lightweight racing bike, it's likely to twist in the clamp. At least that's what I've found.
Having said that, I wouldn't be without it. It's a great and a bargain at the price. I highly recommend it.
