I've put this on 16" barrel 5.56x45mm NATO, .300 Blackout, and .350 Legend AR-15s. The 30mm objective combined with unlimited eye relief is a welcome change admitting much more light and giving a wider view compared to sights with a 20-22mm objective such as the Romeo5 and Romeo7S. In spite of the battery compartment, it has very little clutter on the sides or top to obscure situational awareness view around it. The next closest in the 1X red dots I've used is the 25mm objective on a Primary Arms MD-25 ACSS. Its design is nearly a clone of the Aimpoint Comp M4. Housing is very durable and definitely not fragile.
Red dot is crisp and its brightness adjustment range spans all the levels of lighting range I've encountered, indoors and out. Set to an appropriate level for the ambient lighting, I've never had to hunt for the dot. Parallax is nil. Dot stays on target. I don't have NODS, and cannot speak to its night vision settings. Automatically turns itself off if left idle for a couple minutes and comes back to life immediately when picked up, without any delay. Comes with honeycomb front filter to prevent objective reflection back toward target, and helps deal with glare from bright light sources in front of sight. Presence does not noticeably reduce light coming through. Quick release works well and is easily adjusted for proper tension. I've not lost zero when properly installing and reinstalling it in the same location on the rifle rail.
Size and Rail Real Estate:
This is a full-size sight, with the corresponding weight of one, especially with its battery and its beefy, very durable housing. Its length will consume a sizeable part of the upper receiver rail. If combined with a magnifier, depending on magnifier length, the magnifier may interfere with a BUIS, even if the Romeo7 is put as far forward on the receiver rail as possible (it should not extend out onto the barrel shroud rail, if there is one over the barrel). I've combined it with a full size Juliet 3 (not the Micro), and it fits, but the BUIS cannot be deployed unless the Juliet is flipped to the side out of the way. The rail will be crowded. Those for whom weight is the highest priority should look at smaller, more compact and micro optics. Its 30mm objective with its benefits and optical train are a tradeoff with size and weight (e.g. Romeo4 or Romeo5).
