Second thoughts - UTG Pro 4.2in ITA CQB Reflex Micro Red Dot Sight w/ Integral QD Mount

My first review came after just 1 outing with this sight. Was pretty easy to get sighted in and fired only about 20 rounds as I had my family out as well and had to keep eyes on them. Bought a second unit just last week for another
build and expected the same results. Well not so fast. After 30+ rounds sighting in I gave up trying to get it to zero. It was all over the target. Then I brought out the first one and it was no longer zeroed. So from the first time out to my safe and back to the range couple weeks later it was no better than if I had just pulled it outa the box. So as far as the dot both red and green its fine. But if it won't hold zero then you can judge that yourself.
I returned the second unit.
