It is very well apart is never extinguished. I'll see the use battery life (3). Maybe a little large for those who do not want something really compact. Behind, 3 small magnets allow the "stick" in the fridge, cupboard or other. On my fridge, these magnets strangely leave a mark. The beep is perfect !!! You'll hear it for sure. The color (turns green the last minute, last 30 seconds orange and red the last 10) is a gadget but you get used to "playfully". Anyway, this option is not mandatory (is On / Off button). The downside may be that the display is not optimal (dimmed) if you really look at itself. It takes a very slight angle to distinguish the black numbers. All this said, it is an excellent product of very good quality I recommend.
