I have a couple of the Uni-T clamp meters for at least 4 or 5 years, they've been fine and they've stayed accurate. If I was buying an MFT I'd be investigating how easy it's gonna be to get it calibrated in SA and whether there's service and repair available.

@Dylboy The non-trip loop testing is a bit hit and miss at best. If the circuit has a lot of standing leakage the tester can sometimes trip it anyway. Also with more and more A-type earth leakages being used it also causes problems with non-trip impedance tests.
