Fine grip, I have other sets with the lights but needed a lightless set for my practice poi. They work fine, very pleased.
Grips are grips, they're a good product. The big deal was that shipping took far less than half the time estimated travel to Canada. Bravo!
This knob does what I expected as it is sturdy enough to hold a knot. It has a nice texture for grip.
Like them better than POMs
These are for the inserts not the capsules. I was unaware there was a difference. They didn't make make it clear in the description, and they don't sell the ones for capsules by themselves.
