We found the ball a little big so it takes a bit of time to get used to it.
But it adds a certain something to the dynamics
Easy breathing, so good for beginners but the strap could be tougher and quality could be better overall.
An easy to use gag with good fittings.
Pretty good for the price..
It allows you to breath well, which is great for beginners but those who want a decent gag might want to purchase a better quality.
