Nice. I bought this one for my Note8 and it works quite well on my monitor.

Gets a bit hot, but the phone itself warms up only a little.

I like the form factor of yours better. I want to throw together my own stand with a little fan, and the design of yours seems more conducive (longer cable, extra port). I'd have paid the extra 10 bucks for it. Oh well.

I have a Logitech Triathlon Bluetooth mouse, so I can switch between 3 different Bluetooth devices with just a button press. Quite useful. That, and a Logitech Bluetooth keyboard and a Dualshock 3 rounds out the setup.
