I bought this tom holder a while ago, for my Millenium MX-200 8" tom.
For the price it has, you can't go wrong. Even if it doesn't last much, the price makes up for it (i've had mine for a year, no problems so far).
The material isn't very resistant (can get some dents from clamps and such, pretty easily), so be careful with how tight you use them.
They are pretty standard, so i am pretty sure you can use them on some old pearls too.
This tom holder is suitable for kids or beginners, if you're an advanced drummer or a pro, you should definitely be looking into something more expensive and therefore more robust and resistant.
Pros: cheap, does the job well
Cons: not very resistant
