I was sceptical purchasing an unofficial Switch controller replacement. The original controllers I had with the switch didn't last long which was really disappointing. I looked across Amazon and eBay for. Replacements but offical ones were really expesive and it felt like a gamble going for these. How wrong I was.
They came with a 40% discount so only cost £20. When they arrived they were packaged well and I slotted them onto the switch and off I went. Simple to get up and running and look great. Slightly bigger than originals but fits nicely on the charging dock still.
A couple of things I was looking for from them that are worth noting:
1) the controllers charge when on the switch and in the doc, they don't need charging seperately.
2) functionality-wise, the motion element works a treat.
Also, the controls come with a central price that makes it into a handheld controller. Cooler than the original and easy to hold.
All in all, cannot recommend enough and will be purchasing more when on offer again.
