Bests & Worsts Reviews from Amazon

My first reaction was that this is a good and usable product. I cleaned out the tub o' batteries that I had been using and as I took the batteries out of the tub, I used the included handy dandy battery checker to see if I had any bad or weak batteries. My first problem. As I checked the batteries, I was running about 30% weak or totally bad. That surprised me as many of those batteries were in the original packaging. After some more weak or bad batteries, I decided to check them with my older but normally very accurate battery checker. Of the 23 batteries that had shown as needing replaced my older battery checker showed 21 as being way up in the green. So that is a problem. The battery checker is useless as it does not show actual battery condition. I replaced the included battery checker with my old one which fits and has some room for a couple more 9v batteries and put the included battery checker in my kitchen junk drawer. A very appropriate place for it. My only other complaint is that there is room for a kazillion (that's an official measurement) AA batteries an not enough room for C and D batteries. And 9volt has limited storage also. But all in all the concept and end result is much better than my old version of the "Tub 'o Batteries" and I'm glad I got one.
