Review on Fireproof Battery Organizer Storage Case: Waterproof & Explosionproof Safe Bag Fits 210+ Batteries - With Tester BT-168, Carrying Container Bag For AA AAA C D 9V Lithium 3V Holders by Junee Mauck

Really appreciate the included battery tester. Getting all those loose batteries together and giving them a check before storage is very handy. This is my first battery storage box and it sure is nice keeping all the batteries I have together for easy access. What would I have different? I would reduce the rows of AA and AAA and create some extra D spots. This isn't a criticism just an idea. Kudos to the manufacturer for taking the design time to make the bag fire and explosion proof. (from bad batteries) In other words this isn't just your plain nylon battery bag.
