D-FantiX Battery Tester, Universal Battery Checker Small Battery Testers for AAA AA C D 9V 1.5V Button Cell Household Batteries Model BT-168

IT seems to work as it supposed to.

Great battery tester!! Works on all types of little batteries.

It's works a little lightweight

Best tester I ever had. Very easy to use for more types of batteries than my previous testers.

my son likes it.

Considering the majority of users are right-handed, the meter is on the wrong side as you need to hold the battery (no cradle at all) and manipulate the tester. Just a slight dimple along the seam line would have been nice to keep the battery in order. Can't beat the price though.

It is tricky to use. Battery slips off and you have to line it up perfectly to get a reading. I think there is a better version out there. It's ok in a pinch.

Is difficult to get to read battery to see if any charge left

pretty accurate but hard to use, vary awkward.

Another tool masquerading as a useful tool. Needs a wider %26 deeper base to lock the battery into %26 locking slide. Because of this you do not get an accurate read of how much power is left due to it taking three hands to use %26 not having the battery locked %26 stable in order to get the reading.
