I've been using mine often as an auto electrician, but I don't work flat out so it's not used every day. The voltage accuracy is brilliant.
It happily measures micro volts (after the decimal), so when power is flowing across a fuse, I can approximate the current draw from the voltage drop. Fuses act like a current shunt, but the reading is very small and changes for each fuse size.
Hoping for a chance to use bluetooth or logging on a job. It works well, given it uses BLE to save energy. That gives it a refresh rate slower than the LCD, but it's fast enough for many things.
I get slightly different diode voltage readings between 3v and 15v. For example, an IR diode reads 1.038v (3v) or 1.131v (15v). To be fair, accuracy isn't specified for diodes. Maybe the PTC affects the reading too much.
I'm glad that this meter has worked well for me. With firmware v2.04, it's given me no problems and I like it as my main meter
