>> I also bought a laser thermometer from China ….
I bought an unbranded digital multi-meter from a market stall several years ago for £3.50 (he originally wanted a fiver, but let me have it cheaper as he'd had a crap day).
It was a tiny little thing, but perfect to throw in the glovebox in case ever needed at the roadside to check a blown fuse, etc.
I took it into work one day and did a bench test against our calibrated Fluke multi-meter. Results were like for like. I don't think I'd ever risk checking mains electric with it though. The test leads and probes were very flimsy. Fine for low voltage applications, which was really what I wanted it for.
