I bought this for my timer CP students can see the time they have to do their job. Magnetized on the board (that's great not need to find a corner of a table for the asking!), It allows them to be aware of time passing very clear way for them. This is particularly useful for one of them which is very distracted and never get to finish his exercises! The timer is well thought out, I was afraid to be a little too small for use in the classroom but red zone makes the time remaining very readable even for students who do not have the nose above. It makes a little noise but that's normal for a timer! Frankly when you see the price of some time timer on specialized sites I am very happy with my purchase, very good value in my opinion!
