Not great, but good - Millett Multi-Dot SP Electronic Red Dot Sight

I purchased this item for use on my Mini-14. It was just the right length to mount in the Ruger rings on the rifle. The dot projected in the scope is not a perfect dot; it's somewhat irregular in shape, but I can live with it considering that I bought it for use on varmints at ranges to 100 yards. The variable brightness works well and I boresighted and zeroed on an overcast day. Boresight was at 15 yards, zero at 50 and confirmed to 100 yards with acceptable accuracy. Since I'm not trying to drive tacks with it, I was satisfied with the scope's performance as a zero-magnification optic. I will monitor the dot for signs of deterioration or further irregularity because I wouldn't want it to be any worse.
