I've only been using these for a couple minutes, but immediate noticeable differences for those who care: -The buttons/joysticks aren't audibly clicky! They work the same, they just don't make noise, and personally I like that a lot more than noisy ones.-When I slot in the Green (R) controller, the switch recognizes it as a red one. That isn't really a huge problem though, just slightly disappointing. I don't know if that's just a problem with mine, or a problem with the switch, but I'm already over it.-The rumble isn't the switch hd rumble mumbo jumbo, which again I don't really care about. But if you're gonna play 1-2 Switch, the one game where it matters, maybe these aren't for that.-The Y button on the green (R) controller needs to be pressed a bit more firmly than the others to respond. I'm already used to it, but it's good to note, and honestly most wont notice it. I'm a light presser.-The rumble is a bit loud, and when playing a game that has a lot of little rumbling like smash, it can be obnoxious, since it can only rumble at one loud-ish volume. Though in most games, I think you can turn it off, or you can turn it off for your switch if it really bugs you. Personally, I don't mind it too much.-After a bit more playing, It seems that there's quite a few bugs with my green controller in handheld mode. It doesn't seem to be charging on the console unless its docked, the motion is weirdly drifting unless its detached, and the color isn't processing correctly. it could be a problem with my switch, but im not sure, since its only with the right controller. however, it performs just fine in games that don't really need motion, or if you play with the controllers detached.not exact, but for $40 instead of 70? still definitely worth it if you're a casual like me!I bought this because I was not willing to pay 79 dollars for the Nintendo joy cons. I kind of expected to get a cheaper quality but these are almost exactly identical to the Nintendo joy cons! I definitely recommend!I got these as a replacement to my Official joycons (Joycon Drift be damned!!) and other than no amiibo NFC reader they work great and work just like the official ones for a fraction of the price!I liked how quiet the joycons were and the colors but got drift stick 30 minutes into using them. Super disappointing.Edit: Their customer service is very good. The seller reached out to offer a refund without shipping back the product. Unfortunately I had all ready been to UPS but I appreciate the effort they put in to making the customer happy.These get the job done. They look and feel like the original switch controllers and best of all there is no “veering” issues like there are with the Nintendo joycons.This product synced up easily and immediately with my 1st generation switch. I am only a casual gamer, and it works fine for me. I am very happy with this purchase and would buy again in different colors!Perfect replacement for the original joy cons that were not working for the game. Once replaced with these it was back to working.They feel and work just like the original. My son immediately started playing and he loves them.Me gusto, me funcionó perfecto. Excelente para mi Nintendo
