Eats batteries overnight! - Sightmark Ultra Shot 1x34mm 4 Pattern MOA Reticle QD Digital Switch Red Dot Sight

Have had for 3 yrs. Hate it because the batteries are hard to load and must be removed after every use or else they are dead next time the gun is picked up - and that's after I turned the thing off. Tape the 3 batteries together first before loading with a small strip of tape, otherwise you will use tweezers to keep them from flipping over while dropping them in. Miserable; must be done at the workbench and not out in the woods
