Review on eXtremeRate 7 Colors 9 Modes Button Control LED Kit for Nintendo Switch Joy-Con Controller - Multi-Colors Luminated ABXY Trigger Face Buttons - JoyCon NOT Included by Jonathan Fernandez

I'm pretty good with electronics and thought it would be a good idea to add this mod. Well, I was half right. First of all, I would like to say that I followed the installation video to T. The left joystick is easily installed and works. When it came to getting it right, the problems started. As shown in the video to test it before installing I did this and then proceeded to install after I was done, it didn't work even the sidebar didn't light up. So I bought another one and the right side passed the test too, and then I moved on after the install was complete, it stopped working, it was literally the same result as the first one. So, against common sense, I bought a third one and it failed the pre-install test. I hate leaving bad reviews but I've already bought three and the right side still doesn't work. PLEASE HELP!
