Seems like success. I bought the kit but I broke one of the battery strips, did not have the iopener so I used a container with hot water inside to warm instead of that. Still had to lose a lot of time with the removal of the battery. Secondly, I assembled the display wrongly two times before succeeding - very small structures and one of them was constantly badly connected. Had to reset the device two times before everything was into place. All the buttons work. The battery charges and I have calibrated it. This was the first time I ever fixed anything. Very neat packaging, with extra screws and a pack of gummy bears lol.
