The silent alert is not really silent, otherwise all good.

I set the timer for a few years and am overall satisfied.
Small, light, easy to use, really perfect for my purposes.
Since there are already quite a few reviews, I will not go into any detail, I will briefly mention a point that I have ever seen anywhere: the vibrator is relatively loud, that bothers concretely in a silent room he other (meditate for example, ) most certainly. An alternative would be the flashing mode, but it works for me, for others maybe, I do not want to overstate so.
