As advertised, biometrics work about 75% of the time then need to be refreshed. Key code works every time. Decent size safe, you can realistically get about 4-5 long rifles in the lower portion (scopes make it tricky) and 5-7 pistols in the upper portion and the door holsters combined. Works well for what I needed based on my size constraints.

I've used a large number of Monstrum products. (Red dots, mounts and scopes.) So far, no problems with any of them. They are all outstanding values for what you get. I'm very happy with them all. The illuminated reticle works great on this scope. You get a choice of green or red reticle in many brightness settings.

Sure, there is better gear out there, but you pay a ton more for it. In an emergency you will need to stock a lot of cheap, but reliable guns and sights in the deep preps. I call them Katrina guns. They have to be disposable; because gov will set up roadblocks in SHTF, like they did in Katrina, and take your guns. You will get no receipt, you won't ever get your confiscated guns back. When your guns are confiscated on the road, you go back home and grab another Katrina gun.
 
Monstrum gives you the opportunity to stock a lot of deep prep weapon scopes and gear on a low budget. Thanks, Monstrum for making decent products that work and are affordable.

Great first red dot. It’s simple to install and easy to use. I love the price and would recommend this product to friends buuuuutttt with that being said I do kind of wish I would have just saved up a little bit more money and got a better red dot.

It would be nice to have it auto turn on and off. It would also be nice to have longer battery life.

I also feel like the first 5 brightness notches are completely useless. Idk when I would ever use those setting because I can’t even see the dot in the dark on 5 and below.

I didn’t think turning the dial to turn it on would bother me but it actually does and I feel a little paranoid about the battery being dead when I go to use it.

easy to operate. Very accurate . I highly recommend getting one.
