Not bright enough! - BSA Optics Illuminated 1x30mm Red Dot Sight

RD30 BSA Red Dot Scope works only fairly well in very low-light situations. I have one that I had bought previously from a different supplier, and it works well. New battery didn't help. Very disappointed. Otherwise, the scope is easy to mount and easy to zero and makes the gun very accurate. It has 11 intensity settings, but only the top settings are useful at all, and then only in low-light conditions.
