I didn't fine this thread until after I had ordered the Invisible Shield. I got nervous and didn't even open it for a week after receiving it. I got bored the other night (and you know what happens when you get bored). I pulled the battery, reinstalled the battery door and went to work. I took one piece at a time, used plenty of the solution (to allow for sliding a section into the coreect position. Then I would use the squeegy to get all the air bubbles out. I allowed about 6 min before moving to the next section to allow the piece to begin to dry. I left the phone unpowered overnight per instructions. The results are great. I agree abou this being expensive compared to other products of it's kind, but the results can be very good.
