Amazing surprise with this controller, feels solid, plastic feels good, very durable, plastic feels like the plastic of the PlayStation controller, a good alternative to the pro- controllers, but at half the price. Connection / Sync: Very easy to connect to the switch for the first time, completely wireless, no need to connect the cable beforehand. After 3 seconds, press to connect to the switch. The connection indicators look good. The wake-up-on-plug feature works just as fast as the cons. Few bad things, controller search/seek never finds the controller when it's off, just shows? when you try to find If your controller is on and has a "search button" attached, let it vibrate. Changing the vibration level is very easy and nice when you change it, but when I play, the vibration feels soft and very quiet because the vibration of the reference PS4 controller feels 2 or 3 times stronger. The thumbsticks feel good, firm movement, the thumb cap is slightly larger than the joy-cons thumbsticks. ZR-ZL and LR button triggers feel good, move well and very comfortable, A, B, X, Y buttons feel good, very solid, low noise when pressed hard or fast . The D-Pad feels a bit soft and bumpy, but it is very responsive. In summary, great, great, great controller. This is a great alternative to a professional controller. I think a lot about buying a professional controller, but I bought it to save money and it was a good choice.
