i don't trust anything electric beyond the last time i used it.
the next time it may not turn on, or off, or just stop doing anything in the middle of doing something.
I 've been using the Sig Sauer line of electronic red dots. The reflex Romeo 1 came on my P-320 RX compact with the
shake awake feature. I've change out the battery, once in the last five years. BTW, that my house gun and I never turn the battery off. It's on one of the lowest settings for low light use. The P-320 has suppressor height night sights............. visible back up sights, that can be acquired though the reflex lens.
Also, have three of their Romeo 5 red dots. One on my X-bow and on two pistol caliber carbines. They also have the
shake awake feature and are left on all the time. Haven't had to change the batteries, as yet. For the money, I don't think one can do better for a 2 MOA dot sight. I like them and trust them. The last one, I paid little over $80, new.
BTW, I also own multiple Trijicon reflex/red dots.............that cost 4-5X's as much.
