This novelty kitchen timer is a bit of a fun & decorative ornament to have on a kitchen shelf or window-sill. This gives it the added bonus of always being 'at the ready' and to hand. As described by a previous reviewer, to use it is very easy: simply turn the top half as far as possible, then twist back to the number of minutes desired before you want the bell to sound. The bell is quite loud, though not too prolonged, and having used it now about 10 times, from a 45 minute delay down to just 3, I can say that this is fine for general use. If you want a timer measuring more precisely, however, ie. counting second intervals, then purchase a digital timer (and the batteries needed to power it!). Size-wise it was larger than I imagined, and measures approx. 7cm across the base and 7cm high. To sum up: Does the job, is cheap and cheerful - garlic without the smell!
