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!!!Show more

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.Show more

The DIR-ONE V hasn’t given me any issues. It’s slim, light, yet reliable and solid. Sighting in was easy, the laser is bright, the mounting system is solid.

David, the COO , got my squared away with a couple of questions I had, and went as far as to send me a spare part to play around with for said problem.Show more

Out of the box, the DIR-one green vis laser was easy to setup and co-witness with red dot. The DD MK18 was already a favorite goto but having the laser dialed in made keeping your head on a swivel practical. Solid performance in daylight easy 50yards. Now, just need to donate a few gallons of blood for IR setup.Show more

I purchased two of the DIRV’s. Iv used several types while I was Active and after I retired I have been searching for a designator that was comparable to what I knew and was experienced with. Now that I’m dealing with Gov restrictions iv found that the cost of purchasing what Iv known is far too high, and all the clones out there leave something to be desired. Then I ran across the DIRV. I watched every review that was out there, and then called 3EIR to ask a few questions. Never did I imagine that I would have the opportunity to speak with one of the Co founder’s. The guys that founded this company are experienced, and connected to resources. They have taken their countless years of erperiance in the field of laser development and manufacturing and combined that with guidance and input from experianced combat veterans. Even after that they have been consistently testing and improving their products and pushing the equipment to opperate above and beyond their competitors and still opperate at the legal boundary set by the Gov.Show more

Once I received the units I found that I was not dissapointed. The DIRV is the lightest and most functional designator unit iv ever used that is attached to a medium ranged firearm. I opperate on a AR 15 platform, with a Elcan Specter DR 1-4. This optic sits low, so things that are top mounted often get in the way. The DIRV does not. In fact when im in 4 power I cannot even see it. When im in 1x it is only visible below the entire reticle. The controlls on the unit are so simple and well placed. It instantly has became my favorite unit.
