I bought it to be able to check the time in the dark (as I'm sleep training my 6 months old baby) and it does the job.
You can see the numbers very clear and it doesn't light up the entire room (baby has never noticed).
It's very light weight.
I'm wearing it all the time, take showers and baths with it and so far, so good.
The only thing I didn't like it's that the latch in the belt is black.
