I bought two mainly because I'm dying for them to refill the blue one so bought the green one while I waited. But I'm glad I have two if I play with the other. These controllers work great! Make the game much easier than using small joycons. The vibration is quite strong, but it doesn't bother me. It's very easy to sync with the Switch and start playing. I haven't had any problems and often switch between controllers. It reminds me a lot of the Xbox controller that I also play a lot and it helps me a lot. If only the buttons were the same on all devices *sigh*
