At first I was very impressed with the quality of the controller. You won't find a controller like this for $25. You can assign whatever buttons you like to the paddles on the back, or disable them entirely if you like (read the manual guys). But when it comes to the main function, I bought this controller because it's totally disappointed with the audio jack not working properly. When you speak into the microphone, you can hear yourself speaking through the headphones. Tried three different headsets, with Fortnite, Warframe and even tested in the audio settings of Windows 10. Everything works fine when using the audio jack of the Switch console itself, so it must be a defective audio jack, or rather the controller itself a refund.
