Does what it says on the box! Stops fingers slipping off! Though, the product is very weak and wears down easily. The people who say the triggers kept popping off if squeezed to hard are wrong in my opinion. I was squeezing them so hard my fingers so hard that my knuckles were going white and they didn't pop off.
In conclusion :
Stops fingers slipping off.
Easy to attach.
The grips are easy to wear down so that it will no longer attach.
A bit large for the controller.
These triggers are good and very comfortable during gameplay, however they are a pain when they keep coming off the controller due to the fact they crack very easy... Ordered 2 sets and just ordered another 3 as i cannot get used to playing without them... Someone should produced a controller with these triggers already fitted, or make these triggers from a more stronger plastic... So someone, please do something
