The laser I ordered is of real good quality that is made entirely in the U.S. instead of other lasers that are the same price but made by our adversary (China). I do prefer to have my weapons with either US or European quality instead of tainted by communists. Went to zero the laser and had no issues whatsoever so ever, very similar process on zeroing my PEQ-15 in the military. Had an issue with UPS due to not being at work and not being able to sign for the package but once I talked to customer support they helped streamline the process to pinpoint where my package will be at and was able to talk to UPS on having it shipped to the store. Again will definitely buy again from them to upgrade my weapons at home.

What a great company!!! I have a few 3EIR devices and one of them, the DIR had a couple issues. I got ahold of 3EIR and I believe it was the next day David Rhomberg called and emailed me. It seemed I fixed the issue but then it happened again. David “immediately” got me taken care of and got it all fixed. Thank you so much for that, seriously it’s great to see there’s still really good people and companies still around. I’ll for sure be a lifetime owner and buyer of 3EIR products and sing their praise. You can’t go wrong with these guys and their products!!!

I’ve owned this device for two years and have absolutely loved it. For the cost, it is by far the best option on the market. The ergonomics are fantastic. The device sits flat to the rifle and does not get in the way of anything. The laser and illumination are very high quality. The single button is very user friendly and easy to use in a variety of circumstances. Customer service is phenomenal. If you have any issue whatsoever you can call in, talk to an actual human, and get feedback about the device as well as resolution to concerns. Don’t go anywhere else.

I got my Dirv back in october last year. I watched all the youtube videos on LAMS and after thoughtful consideration I chose the DIRV. And for damn good reason. The illuminator is amazing out to 300-400 yards. Possibly further I just dirnt shoot past 400 yet. Mine has held zero no problem so far after 3000 rounds. I highly reccomend this laser to anyone looking. I had a minor issue with the company I got it from. I reached out to Dave the owner and he fixed the issue immediately. Such a great guy. Spent sometime on the phone with him tonight as well. I noticed my vcsel cover came off. Well one of the rubber bands broke and he is taking care of me by sending me new ones before my night vision class coming up. I will be buying from these guys again in the future. They are that good!!!

Had a severely damaged laser (externally) and Mr. Rhomberg did an exceptional job helping me out with it. The product is definitely built to last and by the damage it endured, for it to still work great even under night vision speaks volumes. Thank you for the generosity and for taking time to help me out with everything. It’s safe to say you now have a loyal customer that will recommend your product to everyone in the gun community.
