I received a pre-owned Nintendo Switch in the post today but the D-Pad is sticky and hard to press, but I can't take things apart, every time I've tried on any console I've not been able to pick it back together. I noticed you could buy replacement shells though with new buttons, but I can't find anything on Google about any service in the UK. Every time I look I get articles from TorrentFreak talking about how hackers were cautioned.
