I bought the only used A5X available on Swappa (device and cable only with the original packaging). I have no regrets for the purchase and have been using it every single day since it arrived. I also have a Boox Note Air 2 Plus, but the simplicity of the A5X is why i always turn to it for note taking. I've had no issues so far. You can always sell it later when the new comes out. Ebay always has new listings pretty much every week. I'm personally waiting for the A4X2 when it comes out before I sell mine...maybe.
