They are the best thing since sliced bread, if you thoroughly
understand fully their limitations.

I find the "beep" facility quite handy at times - plomp it down
close to a circuit you want to turn off, go to (typically
unlabelled) CU, and turn off MCBs until the bleeping stops!

As I have changed and updated the wiring in our house I have
labelled everything as I go. After 20 years of living here it now
means just about everything is labelled. I have even put little
stickers on the top edge of sockets to indicate which MCB/RCD feeds
them.

Yup good move - you quite often see that in commercial setups - each
socket indicating what circuit/phase/CU its on etc.

Possibly overkill in domestic so long as all the sockets are when you
would expect them to be according to the main CU labels. (e.g. if a
"Downstairs Sockets" label on a MCB accurately identifies everything
that is controlled by it without exceptions).

yesterday I ordered some narrow tape so I could label an 'out of area'
socket.

I have a Dymo Rhine and I use 6mm tapes for the 'top of socket' labels.

I've got 6mm tape on order. (P-Touch)
