I've got an android TV box and the remote that came with it was very poor.
I went on amazon and bought the highly rated MX3 controller. It works great but it is so cheap and horrible feeling. The plastic creeks, the button clicks on the back keyboard don't always register and the click of a button just doesn't feel high quality.
Are there any air mouse/keyboard controllers that feel as tight and high quality as the apple TV remote?
I would recommend you the PROBOX2 Remote+. The build quality is really good as well as the performance. I use it every day and I never had any issues. Unfortunately it doesn't include keyboard keys just the air mouse functionality
