Idk what is going on with Jayzens hopefully they replace it because after two years and thousands of rounds mine has not lost zero. I'm on battery number two or three can't remember.

Make sure you practice with it a lot at home (empty and safe of course). Present from holster or low ready and pick say an outlet or some "target" that's in a safe direction and practice bringing the pistol up to your line of vision and "lining it all up" ala finding the dot on the target. after a few weeks and a few thousand presentations it will become old hat. Might not be the best way to do it but it worked for me.

I didn't have to retrain both eyes open as I'm cross eye dominant and have been focused on doing that all along.

FWIW Trijicon says ~25 days at full brightness for their RMR. I run my Romeo somewhere just south of the middle brightness.

I will say that I'm a firm believer in tossing that plastic screw driver they include right in the trash and torqueing that cap down until it sqawks at ya after you replace with a name brand battery.
