Here is a useful accessory! It is just useful, USB A washing machine that does everything except wash.
Here are the Features:
Time, date and alarm clock LCD display 4 different melodies with vibration Hourly chime signal with LED 12/24 hour mode switch. Clock setting by 3 control buttons Powered by USB or by 2 AA LR06 batteries (not included) Dimensions: 7.5 x 7.5 x 9cm Weight: 168g
Very useful, depending on your point of view, I find it useful for those passing through your e-position and asks you what it is, great for those situations where you want to pick a button, but do not know how :)
