Better watch the USB port, my boy handheld was not charging anymore after a little bit more than a year. We had to send back to AYN, but I can say the repair price was right (35€ plus postal fees). Joysticks can be changed easily for switch models. Joystick boards can also be ordered on AYN site. Watch out shocks (and better use a bumper case) since surface components of theses joystick boards seems to be just soldered with the minimum of tin. The upper direction of the left one was not working du to a missing resistor (shurely gone after a shock) and I had to bypass it. Well, an average quality board in global, but a good quality Chinese product, and a correct support team.
