I was apprehensive to buy them after reading other reviews. Someone said sticks don't fit. My experience was great. The problem with joysticks is that you have to press them when you put them on. Difficult. If you don't do this when you reassemble the controller, they won't move properly. I had one that I didn't do well. But the good news is that you don't have to completely disassemble the controller again. All you have to do is click on it after everything is put back together. Problem solved. Everything works as it should. There were no tools or instructions in my kit (which I thought it was supposed to be, but it may have been a different kit). I still had the tools and was watching YouTube videos. It took me maybe ten minutes because I couldn't take the suitcase apart. I was afraid I would break it. But I got it.
