Trijicon makes excellent products, and this is one that’s hard to beat. I had no sight flicker with this RMR even though I didn’t use one of the plates underneath it, and with a little loctite is has been rock solid since day one. Glass is always clear and I bought this model for the purpose of the dot having automatic brightness settings. The brightness change is automatic when going from dark to light rooms, and I never have to worry about it being set too high or too low. Not to mention, I personally feel that the adjustments for brightness on the other models are potential weak spots in the design. Nonetheless, well worth the money. Target/sight acquisition becomes much faster with practice, and you get the added cool factor. Somewhere around 2k rounds through it so far with no issues. Just don’t expect it to make you a great shooter if you don’t put the time in to become one. Practice is all that can make you better!
