I don't know if you've gotten your hands on one yet, so I'll approach this assuming you have not.
I have a Millett DMS-1 and it's a little heavy and long. Mounted on my flattop AR it extends from the rear or the upper receiver to about 2/3 or 3/4 down the handguard.
The 1x isn't really 1x until about 5 yards out; anything closer than that will get slightly magnified, but after that distance things seem to be unmagnified. Works well to 4x.
The illuminated reticle has 11 illuminated settings and an "Off" position, but the bonus to me is that you still have a reticle without illumination, unlike most other electronic red-dot optics. I'm not big into optics, but the only other optic I've read about that has this feature in the Leupold Mk4 CQ/T and that runs $700-800. The reticle is a "dot in a doughnut" circle-dot type with three posts, which appeals to me for my use at this time.
The dust covers that come with the scope are pretty cheap so if you want good dust covers get some decent ones elsewhere.
Not as quick on target perhaps as something like an EoTech or Aimpoint, but it works.
I've put less than 100 rounds through my rifle with this scope mounted and so far, so good. It's already gotten dropped from low heights (fell from being leaned against a table, car, etc.) a couple times with no noticeable damage or change in zero.
Hope this helps.
