“If you like to keep organize & know which batteries are new or used, this is a good way to organize! The build is okay and fits all of my AA batteries of all types, Alkaline, Rechargeable, Lithium no size issue for it at all. If your constantly on the go, this works out so well keeping them all together making it easy to find, and know which ones are used by leaving them out or keeping the old and use together by flipping the used battery the other way. Its still functional!
If you have store them in drawers or cabinets its helps to keep them just as organized. I purchased this for taking it on the go. Easy to replace my flash batteries, no need to search for individual loose batteries, and lets me know how many I have left to go. It’s a good build. Haven’t dropped them yet but they work well.”
