Pros:
It's working well, but it was a little complicated to get it working as there were no explications.You'll need an additional 0,015ohm shunt resistor, connected on the ground/negative.
Cons:
No explication/guide

Pros:
The reading of numbers is very easy, big digits. I was a little confused with needing or not a shunt resistor. Now I think that it needs it.
Cons:
The shunt is needed.
