Works great w/ my astigmatism - EOTech HWS EXPS3 1x30mm Holographic Red Dot Sight

Was initially put off by the battery life compared to a standard red dot, but my astigmatism leading the red dot to look like a chevron, and me guessing which dot was the real one let me to try the holographic, and it works great.

The unit itself zeroed very quickly and easily with the exposed knobs and positive adjustments. I put a magnifier behind it and it lined up perfectly. Very easy to switch. I struggled trying to zero the red dot but realized that my eyes just weren't cut out for it. The circle-dot reticle for me is very quick and easy to use, and the transition was not hard.

Using for carbine classes and general purposes.
