I followed all the safety precautions mentioned: tape, safety glasses… The best advice I saw on this is to put the iPad in the sun for a few minutes. I placed mine on the windshield of my car in direct sunlight for about 5 minutes. I also used the iOpener to keep heat on the edges I wasn’t working on. I was able to easily remove the glass without any shards flying in about 30-40 minutes total. Great advice and safest way I’ve seen to remove broken glass.
