I've also run a few tests now and the resistance & capacitance meter, diode test and continuity test are very, VERY slow. For example it takes about 0.5-1 second for the beeper to sound on continuity and 2-15 seconds on resistance/capacitance, depending on how large or small your resistor/capacitor is. All the other functions are fast at least.
I do still have a no questions asked return window and I am low-key considering it, but then I'd have to fall back to my 1999 count Metex M3800, of which the calibration has drifted so far it's barely usable.
