received but it turns out you can't use the current meter without the appropriate shunt. the description mentions this but it's should be clearer than that

I 've ordered 2 and they work well, one I 've had to adjust quite a bit and give it 4 stars because I ordered them 2 colors red and blue, red everything.

Everything came intact with a shunt, the shunt is healthy 100a has a credibility, but the performance has not checked yet

The first time work was terrible, but when I added the capacitor all stay correct, very correct.

The order was received for a power supply with a shunt at 50A. Works. Recommend.
