It works, but there is a lot of room for improvement. Downloading the software and setting up keyboard shortcuts was easy. My Switch recognized it with no problem and I was good to go. The problem is related to mouse jitter and delay. I wanted to use it with Fortnite but found the mouse too erratic. I couldn't be precise when aiming as if the device didn't smooth out the mouse movements. I thought it was my gaming mouse so I replaced it with a Logitech wireless mouse. The effort was less, but the problem remained. Another problem is the lag. There is a slight delay between a mouse click and the device sending a signal to the switch. This is not entirely acceptable when it comes to shooters. So ok, you can't expect much in this price range.
