It really took a while to get here, but it got here and it works. It could have been a little more accurate with the current measurement on average it's about 50 mA to low making it unusable for a load of less than 50 mA because it will just show 0 A however that is not really it's intended range to it does not really mater that much. I do imagine that the accuracy vary s from unit to unit so you might just get one that spot on.
