It worked exactly as described. At first I had trouble finding a spot to insert the spudger tool but once I did I inserted used a small flat head screw driver to pop the tabs free. I started opening from the side because the case is more flexible there than the top as shown. I magnetized the torx screwdriver tip before I started so I wouldn't drop the screws. My old battery was swollen and I can see why my click wheel was not functioning properly. Over all this took me no more than 15 minutes to complete.
