Works well; is compliant.

This is a fantastic product, very similar to an authentic Nintendo controller. I purchased four and am extremely satisfied. The only minor issue is that using several controllers requires individual setup of each transmitter since they connect to the same receivers. However, once set up, everything works perfectly. Remember to keep pressing the buttons because the controllers automatically power off when inactive. There is no delay with these controllers, and I am thrilled to be rid of wires! I'm ready to play Mario Party 6 and 7!

The well-packaged product was received promptly. Testing was performed, and it works very well, being recognized immediately. The keys are functional. I recommend this product.

The product is good. It arrived with some scratches due to the packaging, which could have been better. However, the seller offered a resolution after I reported the issue. I am pleased.
