Hey Brian,
I have a couple of leapers scopes with the illuminated reticle and they work great. The scopes work great with the reticle left off, however in low light conditions the illuminated reticle makes it possible for me to take a shot I might not otherwise be able to take..
I will admit I don't use the feature very often, however it does certainly come in handy for me at times.
AS for the batteries going bad,,,, I only use the batteries infrequently and they've lasted so far. They are very easy to replace though.
