None at this time - Konus Sight Pro R8 Rechargeable Red/Green Illumination Dot Sight

Have not had a problem holding zero as yet....seems to be a rugged scope, construction wise....have not kept track
of time from full charge ( battery ) to recharge in storage...One review I read stated zeroing was difficult , left was right
and elevation was reversed ? had exact problem with A.I.M. sports, tri-illuminated, 4X32 scope....was sent back and
replaced...no charge....have scope on charge now, been in storage for about 4 months..By the way I purchased your
scope at a gun show some time ago...presumed it was used, but really no way to tell...Scope & all with it, like new
no marks anywhere on anything...O.K. here it is, still had sight illumination when turned on ...green was still bright
red ,not so much....took 1 1/2 hours to bring to full charge...marking on calendar...will keep track of lifespan....
