I broke an LED light and slightly pulled up the layer protecting the screen leaving some bubbles I can’t really get rid of. This guide has no warning whatsoever about being careful with the spudger and making sure you don’t go too deep. The sticky bezel you pry off can be really sticky and difficult to come off (like mine was). If this guide had a simple warning and explanation to be careful about depth of spudger/plastic tools around LEDs and the middle of the screen I would not have ruined a perfectly good kindle and new battery!
