So many design flaws - Vortex Viper 1x24mm Reflex Red Dot Sight

This is an inexpensive optic, but after owning many Holosun models it’s quite disappointing.

First, you have to take the unit off to install/change the battery (not great but common, unfortunately).

Next we have the adjustments. Tiny screwdriver required (that doesn’t come with it) and there are locking screws that you cannot access on many firearms due to the rear sight being in the way. This means you have to remove the optic before and AFTER you zero it - then pray it stays. There are also no clicks and tiny hash marks that are supposed to be 1 MOA. Worst adjustment of any optic I own by a long shot.

They (Vortex) also tell you to zero it at 25-50 yards hahaha! For a pistol?! What are you setting this up for, not defense use at that distance.
