I compared the accuracy to my calibrated Fluke 289 and it's very good for the money! The resistance measurement is a bit slow, but that's ok. Capacitance measurement seems decent. I like the REL function. DC voltage measurement seems to be spot on. The probes are "ok", but I have a better probe set. Can't beat the value! Build quality feels ok, but it's not going to match my Fluke 289!
