Use this Joy-Con as a backup controller for 3 weeks. Advantages: 1. Comfort. The back of the joycon is a little larger, so it's not easy to slide around.2. The battery life is excellent. As strong as the original one.3. The price is super Cons: 1. Straps are very difficult to install and remove. There are gaps between the straps and the joycon as shown in Figure 2. My ring-con cannot determine the correct joy_con although it is set. And the left Joy-Con has a small circle compared to the original. Overall, this is still a good Joy-Con. I love it.
