If you’re looking for real American craftsmanship backed by service that actually cares, look no further. The build quality is phenomenal, the fuction is way better than I imagined and the team behind it delivers the kind of customer service you just don’t see anymore. Dave and his Team goes above and beyond. I am a forever customer. Five stars all the way. Sentinel-IRV

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.
