I know its the design of the Ipod, but the thing is a friggin pain to open, and these tools are basically ineffective. They're really nothing more than a wedge (they will still scratch your ipod up if you're not careful). And you're bound to hurt your hands once or twice.That being said, once the new battery is in, everything worked perfect. Great battery life now. Changed a bricked ipod that apple wanted some ridiculous sum to fix into a brand new functioning one.Just make sure you don't get something in the display when you're taking the thing open. a piece of lint or something got stuck in front of the display screen so I had to open the darn thing back up.
