only moderately useful

I bought because my (then) Price seemed quite favorable, but for the LF-1 six additional batteries: All batteries have these 6 not budgeted 900mAh, but only between 650 and 750mAh, even after repeated charging cycles! In "everyday use" with the option of an external battery charger to recharge batteries, if necessary at any time, this may still be sufficient, but if you do not have this possibility (eg in the outback), and also the running times are shortened, it would be better to a well-known brand (P ..) switch. There's definitely some alternatives, even if they might seem a little more expensive - in relation to the actual capacity of the battery, it pays for itself just stop it!
