Bought one and enjoyed it so much with the setup and features I then bought 2 more for my other firearms. Great product and great service. Could not ask for better....

Have not shot it yet but it arrived clean and free of damage. Mounted it and it cowitnesses nicely with the Romeo 3 flip up magnifier. The only draw back I currently see from my initial look is the field of view through the optic is slightly limited but the counter to that is the optics small size and weight. Trade offs.

The go to cheap reddot. I have 3-4 now. Performs just as good as my Aimpoint T-2's for 25% of the price. Can't beat it.

Really nice sight for the money. Honestly I like them better than my Aimpoint T-1s. Very bright, and very good optical quality / dot image for the price. I like the T-2 better yet, but for the price, this looks like a really solid optic. I got a couple to put on T-Rex Arms new T-1/T-2 pattern offset mounts.

Just bought my second one. Nice dot, easy to install and zero. Both mine were dead on l/r, slightly low. I zeroed at 15 yards because they are on pcc's. At the recommended 25 yards probably right on.

This Romeo 5 is a great red dot. I think calling it a budget red dot is not giving it the credit it deserves. I now own 2 of them. I had a great experience buying from euro optic. I got it quicker than ordering from Amazon. It came to my doorstep in 3 days. That rarely happens with any company these days.

Best budget optic in my opinion. Durable and dependable. I have three of these now on various platforms and they just work. If you can get one around the $100 price range you can't go wrong.

So far so good. I have not used the Romeo 5 a great deal yet but it does all of the tasks that it is supposed to do very well. The dot is easily adjustable and bright to see. Sighting in the dot was very simple. The system works well and has two mounting brackets which allows the sight to be used on a pistol very easily. Great sight!
