Decent accuracy, low impedance for some things

Seems to work well. Accuracy is pretty good (mine is around 90%) and can be adjusted. The internal coil appears to be around 200uH with a DC resistance of around 15 ohms, which is good for some (but not all) applications - a drop of a few tens of mV and a power dissipation of a few hundred uW at full scale (DC).

Pros
  • Ammeter
Cons
  • Doubtful purchase for the elderly
