Shake awake works every time - ADE Advanced Optics RD3-015 PRO Shake Awake 1x Reflex Red Dot w/SAR9 Optic Mount Plate

I've had other budget red dots where the motion feature was inconsistent, so that was the first thing I tested.

So far this one has been excellent. Let it sit, pick the pistol back up and the dot comes on immediately. No button pressing and no noticeable delay.

The SAR9 plate also feels sturdy. After zeroing, I ran multiple magazines through the pistol and nothing moved. Very good package for the price.
