I already have the larger model. the travel alarm clock is not only a bit smaller, but it also includes a (very simple, very cheap-looking) shell to it and the lighting is switched off permanently by a slide switch on the back, as there is a "lock" function. Unfortunately the alarm button not rested one, so he went back defective. Such an error should never really and certainly not occur in the delivery, so 1 point less. Whether the quality control has failed or the alarm clock on the transport its main function forfeited is irrelevant, because if such an error occurs overseas which is very annoying.
