Amazing
Amazing little device, doing a project at the moment where I am measuring less than 5 mA power consumption, and this is doing it pretty accurately...

faulty straight out the box
Looks lovely but faulty straight out the box. Tried it in multiple USBs but unless you push it all the way in and then pull it out slightly it wouldn’t even light up. Even when pulled out slightly you had to hold it just so in order to get the display to remain on.Really disappointed.
