The controller arrived quickly. My son is a nightmare for going through these so I reviewed some other than the original Sony controllers as it's proving expensive... This brand definitely seems to be doing something right as reviews are fantastic .. The workmanship of this controller is really good and fits well in the hand. The buttons also work fine and are very responsive . Battery life is like the original controller, if not more. The controls all react quickly, there are no delays.
My son is just thrilled and very satisfied. Hence a recommendation from me... let's hope this one lasts a lot longer than the last he ordered from a different brand
I also purchased another slightly different controller for my other son based on this experience
