Never liked the design. I got 4 battery containers that ever ready put out years ago, much better laid out and you can stack them. Use C batteries for some outdoor candle type lights, used to use them for flashlights as were D used, don't know anything that uses D anymore, feel C will disapear also. And to answer a question, both A and B batteries still exist, though A may be done now and B rairly used, there are other weird sizes too.
Yes, I was gifted one. It does keep your batteries organized. I already had the battery tester but I could never find it when I needed it so having one in place is nice. What I find though is I rarely need anything but AA and AAA. The Cs and Ds pretty much go unused. I do have one old flashlight that takes the Ds but I rarely use that one because I have a rechargeable that is much brighter and has multiple functions. I can't remember the last time I saw something that took a C. It's been decades. While we're on the subject, were there ever A or B batteries?
Anyone own one? My better 3/4th got it for me for Hanukkah. It's a fantastic way to organize your batteries. Batteries and model trains? Of course! Have a mult-meter? Battery-operated. What else?
This thing not only stores the batteries, but comes with a tester. No more scrambling for them in the utility drawer(s) or on shelf garages. Get it and you'll never regret it!
Happy Holidays.
