ROMEO ZERO 1x18mm is rated 2.6 out of 5 by 47 .

Rated 2 out of 5 by DeafShot22 from Disappointed after a very long wait... Pros: Overall form factor is great with the pistol; The plastic housing is holding up better than I thought it would; The red dot is bright and the window is large for the overall size of the unit. Cons: No bottom cover which is also where the battery is installed, you have to remove the sight to change out batteries and the unit internals are potentially susceptible to damage; The Lens is made of plastic and very easily scratched; Location of the red dot adjustment button is next to the inside surface of the plastic lens which which is fairly difficult to quickly access.

Rated 3 out of 5 by Anonymous from Good I bought it about a week ago, it showed up today so I immediately went to the range. Everything works like it supposed to, no issues there, but the reason a gave it a three stars is because of the red dot "glass". After shooting about 50 rounds I notice some debris from the detonation of the rounds hit the "glass" and scratched the surface. Initially, I thought it was just dirty but to my surprise it was not. This handgun will be my new EDC, but I don't think the red dot "glass" will last.

Rated 1 out of 5 by Issac Franco from Terrible Optic I just bought a P365 XL ROMEOZERO on July 17th and I picked it up on July 21st and I took it home to clean it before I shot it. The 365 was great, its a really nice gun and I have no complaints there, but when I took it to the range to zero in the red dot I couldn't move the point of impact up at all (the dot would not go any lower). I asked for help and the gunsmith could not figure it out either. I would not recommend this optic at all currently. If mine is defective then fine I will see how it goes but as of now, this is a waste of money for the optic, a waste of money for the range time, a waste of money for the gas getting to the range, a waste of money on ammo, and a waste of my time.

Rated 5 out of 5 by Fabro61 from love the size! I waited a month and almost returned it because of the way of adjusting the brightness, but when I got it sighted in, it was awesome! I have never shot a handgun so accurately! I have a friend that almost always out shoots me and I have to say that when we get together,, that's going to change! I cam so excited to be able to shoot a micro, or any hand gun so accurately ! I thought about sending it back an ordering the holosun but that sticks out 1/8" on both sides which I did not wan't in a EDC!
