To expensive to buy new, cheaper to replace broken part.
Without the iOpener it was a fricken nightmare!!! You could over heat the unit with a heat gun and have to buy a new unit or use the iOpener and get it done in about a half hour, just like it says before you buy it. The glass stays together better, even where it is cracked when removing. Great tool, very simple and yet very effective.
Before you even try to remove an iPad glass, jut spend the $20 you will be very glad that you did. Also this nifty tool can be use on all sorts of different units. You will definitely make your money back.
