I have only had the Holosun EPS Carry (green) for a month; and only was able to shoot once at a quick range visit to make sure it was sited in. All I had to fix was the windage, and afterwards it was spot on at 10 and 25yrd distances.
This is my 1st enclosed emitter for a carry pistol and I can see why they are so attractive, with keeping the dust and lint off of the view port. The variable emitter choices, being an enclosed optic, all metal, battery loaded from the side, ease of controls... make this reticle worth the cost.
Absolutely no complaints. I love it way more than RomeoZero (for all the reasons listed above) that was on before. So much so, that I bought another one for my best friend for his 20 year retirement from the Navy which is coming up later this month. Seems like the perfect gift for another 2A-enthusiast wrapping up his military career.
