Excellent for its price! If it keeps disconnecting, request a replacement and they will bring you another one directly. At least, that's what happened to me, as the first one I received was faulty, but they served me promptly!

Very small in size and very convenient. I have been using it for several months now with Anker headphones, it works perfectly, instant connection. It does not consume battery excessively. Also, incredibly convenient is that it has a Type C port to connect a power bank. In short, for traveling and playing outside, it is one of the best. In combination with an Anker power bank, you have endless hours of gaming. Thank you, Nintendo, for not including a Bluetooth after we spent so much money.

Very good job on delivering what you promise. The only downside is that if you have a case for the switch, it requires some searching because most of them don't fit, resulting in having to either use an adapter or the case! Connectivity is flawless so far without any disconnections! It's worth buying it!
