The Silicone Ball Gag from Sinvention is by far the best ball gag I have owned to date and I loved it to pieces from the first time I put it on the day I got it.

The Sinvention Silicone Ball Gag is a very luxurious ball gag that although it has a high price tag is definitely worth the cost in my opinion, the 'band' consists of 2 pieces of thick sturdy leather on each side of a softer but strong piece of stitched leather where the ball is positioned. Those two sturdier pieces are attached to the softer strap via 2 sets of two durable button snaps (which I suppose you could use just one instead of both but it would weaken the security of the gag) though I would suggest not to overuse them as they may eventually lose their strength over time.

The gag is indeed lockable, the buckle is very solidly made and shiny, to lock the gag you pop the stem of the buckle which has a small 'o' instead of the normal 'prong' like many gags do which lets you slide a mini padlock (found at hardware stores as well as dollar stores) through it which provides a very secure experience for you or your partner; though due to the aforementioned snaps the gag can also be taken off quickly in an emergency which is a good feature but kind of renders the lock a bit less potent.

The silicone ball has a slight give to it, is a decent size that will keep most chatty partners silenced (it silenced me quite well and I have a medium sized mouth) while still being comfortable, it can also be easily sterilized via boiling as well as a 10% bleach solution; however due to the fact its worn in you or your partners mouth that may not be advisable. Also, the ball does have a slightly noticeable line on it where it was placed in the mold, but if you position it right you won't really be able to feel it; this may turn into an issue in the future as proven by some of my past ball gags.

I have noticed some slight shedding (very very slight) of the harder leather as well as a bit of 'stress marks' on the band with the sizing holes, which allow for plenty of options and will fit almost any head (mine is HUGE and it fit snugly on the second last hole), but overall its been holding up quite nicely. It may be worth mentioning at the very tip of the sizing strap, the Sinvention logo has been stamped on the exterior of the leather strap but is hardly noticeable if you aren't really looking for it.

I really can't stop admiring how strong and perfect this ball gag is compared to other ball gags I own & have owned, I may eventually invest in a second one despite its high price as it really is an amazing gag.

This is still my go to ball gag. This gag never stops amazing me in how sturdy and well designed Sinvention made it, the fact that it locks will likely eventually come in handy too if I find a partner to play with in the future; don't waste your money on cheap rubber ball gags with cheap straps, get something thats built to last and top quality!
