Buy what you will use.

I have found this meter (my 2nd, the 1st was gifted after much use) to be everything I needed. I choose the AM33B over the AM33D. The AM33D, like many meters, has an abundance of amperage selections, but that is the one thing I find myself never measuring...AMPS. The AM33B has three amperage settings, more than enough, and they included three battery test options instead of all the amperage options. I find myself checking battery voltage a lot what with rechargeable batteries and standard batteries. Duracell had a squeeze option to test the battery but that went by the wayside. Yes, this is overkill if you're only going to test batteries with it, but voltage options, resistance options and diode checker are something the average person is going to use. Another positive thing is the two AA batteries, vice the 9V battery in the AM33D. The backlight and hold buttons are excellent options. To say this is an entry level multimeter is just plain wrong. Buy a meter that has the options you will use, not a meter full of uselessness.

Easy to use

Purchased for testing the batteries on kids' battery powered driveable cars. Easy to use. Accurate reading. Happy kids with more time driving their cars around the neighborhood with enough battery power.
