I'm on a DMS-1 crusade right now as I've recently picked up one for 50-200 yard use on an 16" AR.
I'm sure you'll see my gushings on other scope related threads
It really excels at 100 Yards and below. 200 yards is still useable but I'm a crappy shot so no use blaming the equipment

.
Things I like:
1. The price
2. The build quality
3. The ergos
4. The reticle
5. The magnification suits what I use a scope for.
6. The dealer I bought from (P&D Ent.)
Things I wish were not there (but not a reason for
not picking the DMS-1).
1. The weight.
2. The reticle washes out to black in daylight on bright surfaces
3. It's not a direct replacement for Red Dot (but I/You knew that)
I plan on keeping this scope.
100y 1x mag, minimum intensity
100y 1x mag, maximum intensity
100y 4x mag, max intensity shows contrast between white and dark background (washout)
100y 4x (4:30 pm Eastern, February)
(Um scope wasn't mounted for these pics

)
When the red illuminator fully washes out... which it does a lot.... it just goes black.
in pics 3 and 4 the crosshair appear redish... this is just because I wasn't square with the objective when snapping the pic.
