I ordered this a while ago, and it just arrived. I have a multimeter which, as far as I know, is still working, it just needs a new battery. Unfortunately, one of the screws that needs to be removed to change the battery, won't budge. I tried WD40 and variations thereof, but no luck.
So I ordered a screw removal tool, which arrived today. It comes in various sizes for various screw sizes.
It's something for me to look forward to when I get back from Oxford.
