Comes in very handy, especially when checking the batteries in a device that requires multiples.  It can not measure the CR123A battery.  With a slight modification, it could measure those also.

It's very handy...the light is very bright watch out if you flag someone..

The battery has to be carefully positioned on the bump in the metal contact, or you get a false red ("dead battery") reading. But it's great to be able to check if the batteries I find here and there in the house are used or new.

Really handy to have around, they handle a fair bit of current and the included diodes are great for controlling voltage spikes coming from motors/coils. Shipping on these claimed it would be a really long time, but I got mine fairly quickly.

Been wanting one of these for quite a while.  Now, when we need a battery, we go to the Caddy, and find the battery there.  The battery tester works great, and this caddy has room for all kinds of different batteries.

Very handy and portable; never know when the "ole" battery is going to be dead and you need a start; comes in handy for helping those in need (if they ask for help) recommended for peace of mind for everyone

Very handy for carrying spare batteries for whatever electronic item you're using, camera, radio, scanner, etc.  Also for storing batteries in that kitchen junk drawer so they don't short out against all the other stuff you keep in there.  They're reasonably cheap so why not?

All of our batteries are in one place instead of thrown in a drawer.  Divided by sizes.  There is a "working" tester built in that really does work!!!  Check your batteries before you try to use them.

Handy little gadget!

Great utility for the closet.  Nice to have all my batteries organized and in the same place.  They do NOT fall out when hung on a wall, there is a slight angle to the slots.  4 out of 5 stars because when full there are 2-3 spots that will not fit a AA or AAA battery.  Strange but true.  Wouldn't stop me from buying another.  Haven't used the battery tester yet but it's nice to have.

Works GREAT , the only down side is that you have to keep an eye on the light because it tends to turn on by itself and drains the battery, or screws off.

I bought this when my battery died for my last Dewalt drill.
For just a small amount more than a replacement battery, I got this set so I now have 2 batteries,a second charger and case that will work with my original drill.
Very handy as I use one with drill bit and the other to drive screws when doing projects

Nice idea!  Love having all sizes batteries in one spot AND, being able to check those odd ball batteries that seem to appear on your desk or counter!

The batteries alone made this deal worth it for me.  They came in very handy while on vacation recently, I never had to worry about recharging with 2 spares available.

A handy unit for charging those AA/AAA and 9V Rechargeable type batteries.  I like the LCD that reflects the charging of, and on, each battery.  The only reason I did not Review this as a (5) star rating is because: The unit came with several scratches across the length of the LCD Lens cover (even though it had the typical clear tape type covering over the LCD as received), thus demonstrates a bit of poor final handling by the MFR., and the unit takes longer to charge batteries than what is indicated in the advertising - while it also becomes rather warm.  The batteries I've charged to date one time now, where brand new-never-used Amazon Basics AA 2000 and 2400 Mah NiMh batteries, which already had a half charge.  The unit is otherwise handy, and will do the job overall.

Have had this for two years, and love it. Just a handy tool to let me see how my battery is holding up. I live in Arizona and the long hot summers here play havoc with battery life...cuts about a years worth of service out the battery life. Using this gizmo, if the yellow light stays on with no load on the battery other than the standby functions, I hook up my battery charger and give it a full charge and check the water levels....has kept my present battery alive past what is normal for AZ.

It's such a relief to know the status of batteries for sure.  And so far, the capacity it shows has borne out in usage, every time.  I'm buying another one as a gift.

good cost, but it must be hard to ascertain that all batteries will perform when used - I appreciated their caring
