Actually, I used my thumb nail - which is pretty strong, a credit card, and a short quarter inch wide flat screwdriver. I started at a top corner and worked around it. There is double-sided sticky tape around the inside where the case meets the screen, but no glue or welding. At the bottom, just below the centre of the screen, the is a tab that locks into a slot on the under case. You can release that tab after you unstick the bottom tape by twisting the top around the tab until it releases. Have at it... but don't blame me if something breaks
