Thank you seller! Good quality goods. Fast shipping. I recommend the seller! Thank you for your success in the new year!

24.12 ordered, 4.01 has already come to the Mail. Very fast. I ordered with this another one, easier with the shunt at 50A. At the first tests, the current was 3 times different from the real one. Contacted the seller. And he opened my eyes! It is necessary in the settings to correctly install the shunt type. After that, all the testimony came to normal. As a load used 6 auto lamps of 21 watts. Of the shortcomings, I can note that it is necessary to use 4 wires. In fact from one shunt terminal go 2 wires to the medium terminals of the meter. And what prevented them from being united? I recommend both the product and the seller!
