I ripped 1 the first time i took it off. The gray one is no good for ps4 as u carnt really move the stick at all. The yellow one are ok dose a job but i played with battlefield 1 and u can alter the senseativity in setting so dont really make much difference
It's just foam cut out to fit round your controller in a round ring and they charge you over £8 .00 for it when the t cost the about 2pence to make what a rip off
