Ergonomics are good and deserves 5 *, bravo to the small internal battery (supplied and installed) which saves all settings. the sound is consistent with a radio alarm clock so between 3 and 4 * The number of frequencies captured FM is low in quite difficult conditions but my previous camera was better with a small antenna wire that does not exist on this device so 2 * In all 3 * but why Sony did not put it to you an FM antenna (possibly in place of the AM antenna) while the temperature probe, it is after about 1m without a large wire interest?
