Unsuitable for Android

Seeking for a long time after a keyboard for my HDMI TV Stick is based on Android.
So far I have not found that very important for Andorid devices feature pinch-to-zoom allows. That's when you zoom in to the two fingers together or move apart.

I'm using for months Logitech K400r and am thoroughly satisfied until pinch-to-zoom.
I've tried various models of Donzo.

When Microsoft keyboard there's a problem actually faulty design: the mouse buttons are integrated into the touchpad. That's ok, but once you put a finger on the button, you can move the cursor no longer with the other fingers though the keyboard is considered multi-touch! My K400r does not have this problem because the keys are mechanically separated from the touchpad.

Add to this that the movement of the cursor is very erratic at times, as if my fingers would not have a good and constant contact with the touchpad. K400r also has this problem and cursor movement is even and "smooth".

The list of negative impressions I close with the "tactile feedback", so typing feel.
Microsoft: too short way too soft, no clear pressure point
Logitech: the path is longer (and acceptable) and the pressure point is better defined for me so much more comfortable when typing.

Two stars only because I could find a few good features sure how that worked the keyboard by plugging in the USB transmitter immediately.

The bottom line for me clear no-go and not advise: the unit returns today
