A mate called me to tell me about these, so I brought one, it seems to be reasonable quality and comes in its own storage box, can’t go far wrong with that for £8.99.
I have one for taking readings of the OLE, not a bad piece of kit, does seem to eat batteries though?
I bought 2 of these about 2 years ago. both no longer work and are not in once piece seem to have feel apart while using
that makes me feel better about mine.used for about four hours a day every day for nine years and still as good as new.
