Involvement:Expert (understands the inner workings) - Ownership:more than 1 month
+/- Accuracy compared with a multimeter and a tiny resistance which is pretty okay imho.
Small and easy to measure no switches to deal with.
measure almost all kind of batteries
Even RCR123A LiFe can be tested with it and same accuracy as much expensive other devices
none so far
Checked against a 1k ohm in series on multimeter and the results are pretty near which means trustworthy enough... not sure if it has some internal resistance but the measures tests indicates that it has.
it is really cheap... why dont buy it?
I probably buy another one
