I believe the right stick is broken as it moves on its own during calibration. I haven't used it in a long time, and due to the above issue and the uncertainty of whether it starts up normally, please purchase it as a junk item. I have cleaned it briefly, but it is generally dirty and may have dust inside. The straps are almost unused. I will wrap it in cushioning material and ship it with water damage protection. No individual sales. Immediate purchase is possible.
