It works in my holster Great!!
This ball is great as a spare - and the price is good. I especially like the allen key socket being in the ball - this makes attaching the ball to your device much easier. I do wish that this ball was included with all of the mounting kits that require it - the other pieces are worthless without this ball. As a replacement, I have no problem with the price, but it's a little ridiculous to sell the mounting kits without this ball.
Works as advertised
