I have to say, this is the BEST item you can buy for the price. I originally had Duracell CR123A batteries, which costed like $17. This set is $12, you get two batteries and they're rechargeable??? I love this thing, and so does my team. Our team (Cookie Jar Security) did a video review of this item.
Enjoy,
