does not get too hot when charging the phone (it will get warm, but that is to be expected).- takes about 1.5-2 hours to charge my phone from 5% to full (this depends on if you are currently using your phone or not).- can use with a glass screen protector (works fine with my supershieldz)

Something to note is that it does not provide protection to the front glass, which some may prefer and some may not as it can feel jarring hitting your finger against an edge
