I purchased 2 batteries and a tool kit for my wife and for my IPhone 5's. Did mine first as my wife was not about to have me possibly ruin hers. LOL. Mine went off without a hitch. Hardest part was getting off the screen. The ribbon connectors you have to pull off and put back on are extremely tiny so if you're old like me a magnifying glass would be a great help so you can see what you are doing. I then went to do my wifes phone but after about 20 minutes of trying I was unable to get her screen up far enough to stick the pry tool in and pry the screen up. I put it back together and will attempt another time.
