Defender red dot - Vortex Defender-CCW 1x25mm Reflex Red Dot Sight

I do like the picture size of the red dot and the battery compartment on it. But that’s about all I like. I don’t know if I received a defective red dot but as I transition from target to target the dot trails like it has a tail and flickers and is very distracting. If this is the what they are putting out for this price you can buy a red dot for half the price that is better than this red dot.
