I have been using the GMT-12A for a few years now.
It has outlasted three other DC testers (two of which were from radio shack)and has done a better job of OHM testing than any DC multitester I have owned.
I assume you could spend two or three times the money and get a better tester, but
this thing gets into some strange nasty places and performs its simple task every time. Battery life is amazing (I have changed the one AA one time since I have owned it; at least 10 years.) So you would expect the battery to last at least 5 years.
The battery cover slides on, and is also attached with one screw. It has one .5 Amp 250V 3/4" fuse and a spare fuse holder in the battery compartment.

It's a nicely made multimeter (much better than digital). However, I most frequently measure voltage in batteries, and the 10V range is just too wide for that. I'd rather have 3V or 5V instead of 10V.

I bought another brand VOM for my grandson during xmas but it was defective as received..so we returned it to Amazon and purchased this brand..he is away at school and is always working on his mustango G-T when he has time..he loves this new VOM and says it is very easy to use and reliable..so we both are 'happy-campers'...gdm

Decent meter, but has only one range on the ohm scale. Does not measure below 100 ohms, or have an audible tone for testing continuity. Check Sperry meters before buying one of these. They cost about the same, and have better features.
