Product quality? - OpticsPlanet Exclusive Sightmark Ultra Shot A-Spec Reflex Sight 1x33 mm

Received sight Saturday, fast UPS shipping from Optics Planet. Opened and looked over, removed the plastic battery block to see the 4 different reticles the sight has. Selected the circle with dot and powered off. Packed it back in the neoprene case in the box. I wondered if the sight was going to be the right height to use with the sights that are on my carbine. Did research Sunday, opened the Sightmark box again to confirm the mounting height against my research, turned the sight on for the second time, looked thru the lens and saw the circle and dot looking like a moon crater instead of a circle and dot. Adjusted the brightness to every setting, no difference just dimmer. What a disappointment. If a sight that has not been used, just turned on and off twice has the display fail, I cannot recommend the company's products based on my experience. I will be contacting Optics Planet to set up a return and research a different company for a sight to purchase.
