Has anyone used the Ishoot tripod collar?

I noticed this and I'm wondering if anyone on here has used it?

Looks nice and is a lot less expensive than the NOVOFLEX ASTAT-NEX tripod collar.

I actually ended up finding a Novoflex Astat-NEX tripod collar used for $50, so I decided to go with that instead. Fits perfectly on all my lenses.

For anyone else looking at them, I use a different iShoot collar on the Sigma 100-400 dg dn and it works well - no complaints regarding quality
