How about the weight Test?
My original Ipad 2 Glass/Digitizer was broken, so i ordered a new one on ebay, which has beed described as OEM.
After i got it, i recognized, that the material of the new "glass" istnt of high quality. So i took a digital balance from the kitchen to compare the weigts.
The old one, which was already broken and has had noch homebutton, was around 130g. The new one incl. 2 screen foils just had 112.
So this one gets back to sender! Hope ill find an original replacement soon.
Kind regards.
