Too problems in design and reliability - Sightmark Ultra Shot Plus 1x 4-Pattern MOA Reticle Red Dot Sight

I got this for match competitions and dynamic drills, the first problem I encountered was simply mounting it.

Although the quick attach system was easy, it didn't hold the unit securely to the rail and would often reduce precision severely by an inch at 15 yards on a PCC 9mm.

This was absolutely unacceptable.

The second problem comes with zeroing, the adjustments for windage and elevation required a Allen key and yet the mount was a quick attach.

In general; remounting occures less often zeroing, and so this was a key issue in the design that bothered me. Using a key to adjust windage or elevation is a major pain.

Next is the display type selector, the switch moves from left to right and as you select each shape the windage goes off slightly (actually a lot).

The power button function is the next issue, it's easy to turn on but you need to press and hold for 3 seconds to turn off. This is rather inconvenient and leads to suceptability of the unit left on and draining the battery.

The multi cycle of intensity button is also very inconvenient, the previous model had a dial.

Overall I'm very disappointed in this as most of the "improvements" were hassles and reduced its reliability.
