Got this little guy the other day. Excuse the big tank, it's supposed to be for my 22mm Ammit (which still hasn't arrived) Kanger Kbox 70. Not overly impressed with it. It's super basic, and it works, but it's a little awkward and clunky. I only really bought it for the size. We'll see how long it lasts. Had a used one given to me that didn't last for shit, but I was told it was left out in sub zero weather, probably what killed the battery.
