Good picture too! You can clearly see the 11 brightness adjustments. The comparable Aimpoint has 5, but an adjustable MOA.
Heres the school of thought on the MOA. Up close you switch to a larger dot. Why? I dunno, I use my 3 MOA dot at 15 yards to 50 yards.
The 3 MOA is dot enough.
The brightness adjustment is probably more than needed. Now, going back to the Aimpoint again, I have heard it the adjustment isnt enough, but I dont remember if it either doesnt get bright enough or it cant be turned down enough...
So for the price, which it can be found for less than $100, this is a good unit! I havent had any issues with my Bushnell 1 x 32 MP Trophy Red Dot. It holds up to 12 gauge recoil and no problems with it holding zero. Allison uses it to shoot clays with 00 buckshot and I've seen her pick off individual clays when theyre just inches apart. Thats gonna depend on your buckshot too though. Another topic I believe.
