Cuts off and on - AT3 Tactical ARO Micro 3 MOA Red Dot Reflex Sight with Optional Riser Mount 1x23mm

I bought this product maybe 3-4 months ago and ever since the first time I brought it out it shuts off and on it always works until the first shot then shuts off and I can’t get it to come back on. Iv put a new battery in it Iv tried everything. I have it on a .22 so no recoil. Just feels real cheap in my hand the screw to mount it to the rail is really soft and easy to strip. Has been nothing but problems for me. Wish I would have bought other brands that I KNOW are good. Honestly feels like I got robbed…..
