Mine goes through a battery about every 2 months that’s terrible I think it should at least last a year. I use it for my carry gun and if you depend on the Red Dot you might be screwed when really needing it 😡😡😡
I have the same exact problem I’ve put # 3 battery in my Wasp I used Duracell batteries I’ll try # 3 and see what happens unless anyone has any other suggestions???
