I'm hoping to buy some battery operated cordless straighteners for travel (e.g. camping but also flying) but a couple of reviewers on Amazon mentioned they had them confiscated at airport security & didn't say where. Reddit mentions problems in Japanese and NZ airports with straighteners that do not have removable batteries (i.e. all affordable models). Some websites say you just have to put them in hand luggage. Others mention 'flight safe' mode, but those on sale in UK don't seem to have this. CAA page www.caa.co.uk/passengers-and-public/passenger-guidance/baggage/safety-advice-on-what-to-pack/ suggests that the battery does need to be removed.
However, there are numerous mentions in other Amazon reviews of models with non-removable batteries of people taking them on planes, without mentioning any problems. Does anyone on here have recent UK (particularly Manchester) experience of successfully going through airport security with one or having it confiscated? I have a special bond with my hair straighteners, as you can probably tell from the time I've already spent googling this! Thanks.
