Great, all around meter

These are really great meters especially for the price. Unless you’re doing some very specific measurements, or need a special fast response, there is no reason these meters could not do any low-voltage job out there.
I do wish they offered some kind of magnetic holding option, even if it was a little bit more money.

Works great

This was perfect in helping me find a parasitic draw in my cars battery. Only thing I don't like is the auto shutoff after 5 mins. When testing a draw you need it to run a little bit since the voltage is fluctuating.
