Very good display accuracy: + - 1 digit as advertised
For installation: no need to decode the hieroglyphics and Chinese language: tranquil, no instructions!

You can not go wrong if we thought a bit
The son of the torus intensity are short: we can lengthen but not too much: arrange to install the unit near the cable for which one wants to take its intensity (no pb for voltage, one can lengthen son)
