My husband has an amputated finger and often complained that the PS 3 controller was uncomfortable so when I bought the PS 4 I also purchased this.
Was certainly worth it. He says it makes the controller very comfortable to use for extended periods of time and it looks good too which is an additional bonus!
Cheap and comes in a variety of colours etc. Something to suit everything and easily the best buy for the PS4 to date. Added bonus is that it’s cheap aswell.
