I bought this toy because I was looking for a timer that would sound all 2min ... (nothing to do with scrabble in my case) is adjustable in 1 or 2 or 3min.On support on the head and the timer is started, a small light comes on every 10 seconds, a beep every 30 seconds, and an audible countdown for the last 10 seconds ... the timer recovery whenever kon support regardless of whether there is a cour.Fonctionne with 2piles normal (most courantes.je know rained ref.?!) This toy is the size of a cigarette packet (a little larger on the base) A ki gadget timer can be helpful in many cases .. .
