it helps to have a partner when installing the first pick at the bottom. I had to heat my bottom edge 4 times and then hold the front while pulling on the suction cup. My partner was able to get the first pick in and then I could proceed with the rest of the instructions. I agree with the person above that getting the old battery out was a pain. My bottom tab broke right away but my dual side tabs stretched without breaking and I was able to get a pick under the upper right quarter and then use a pry pick to get it the rest of the way.
