I bought the straighteners for the handbag. It is pretty small and you can really take it easily. Even the coated Transportbeutelchen is practical. However the hair straighteners work in itself is not so insanely good. There are no controls for the temperature and the hair is simply not reasonable smooth. Handling I also not very comfortable.
BUT ... you can not compare with a full-fledged straighteners flat. As an emergency option for traveling on a budget, it is perfectly fine.
