have one in 4 moa dot, like it except for a few things:
no manual brightness. it's all auto brightness as far as i can tell.
mounts? doesn't seem to be much info on other compatible mounts for it. would love to have a qd mount for it or have it sit ontop of my acog,or a low mount for my 10/22, right now limited to allen keys to attach/detach with absolute co-witness.
do find that the dot washes out when i have a flashlight on as well though.
it's not an aimpoint micro/rmr killer but does seem to be able to play with the big dogs for sure (minus manual brightness).
battery lasts fine so far, lost the cover for it long ago (how you shut it off I guess)
edit: have a shield CQS not a mini.
