Bought to use on the #25 chainring on a Razor MX650. It felt solid and fairly well built, but the pin in the middle was a bit off center so I couldn't use it to knock the rivets out of the chain (I tried but it just came loose when you tried turning it down). comes with an extra center pin. So if you also have this problem, you can try replacing/discontinuing it. But maybe that's not a problem with a larger chain. I didn't end up using them, but it was nice that the gloves came with it.
