First of all, let me say this is a real help for anyone who plays games for any length of time. If like me, in the heat of battle you tend to get a bit Sweaty Betty then by all means consider buying this simple but effective add-on to your controller. The product itself is well made, clean sharp edges making it reasonably easy to apply to the controller, if in doubt consult the manufacturer's website for quite comprehensive installation instructions. You most definitely need to clean the controller before installation. At the price it is a little bit on the expensive side, but should give years of service, and it was delivered on time.Would recommend to anyone who games for any length of time.
