pvc window - rendering final average

no real problem to disassemble the old glass, taking care to the wifi antenna and seal around (better to buy this ring and also change). This glass is not the same quality as the original, it is PVC. montee once, everything works fine BUT the tactile behavior of the window and the button are not completely satisfactory: the button does not react as origianl, the accuracy of either glass (sometimes actions are triggered when the finger does not touch the glass). My ipad was well abyss so no regrets ... but this is not a new iPad!
