Purchased on the release date, March 3, 2017. I will also include the Pro Controller and SD card. I checked the functionality, and the R button on the right Joy-Con is slightly unresponsive. Other than that, I didn't notice anything. The sticks were also fine. However, when playing Ring Fit Adventure, the gyro controls sometimes drifted quite a bit, so there might be an issue there. I tried calibrating it on the main unit, but I'm not sure if the problem was with the Ring-Con, so I'll mention it just in case. Regarding the Pro Controller, both sticks had a slight drifting issue before, but the symptoms improved after I used an air duster around the sticks. There were no problems during the functionality check. However, please be aware that it might recur. I basically haven't taken it outside, and I've mainly played in TV mode. It's been 8 years since the release date, so there is corresponding wear and tear, scratches, etc., so please understand that. Also, there may be undiscovered malfunctions. I haven't cleaned the small details. The screen has a protective sheet on it. There are marks from the dock and some lifting on the protective sheet. Initialized! This is the initial model purchased on the release date. Please understand that this is a used item. Returns are not accepted. Price is not negotiable. Thank you.
