This is a wonderful watch in every other way but the primary purpose I bought it for was the five alarms and the beeping or vibrating function.  I knew that the beeping alarm may not wake me up everytime, and it didn't (I woke up 1 1/2 hours late).  So I switched to the vibrating alarm.  It woke me up the first time, but this morning it didn't, even though I was waking up every 30 minutes and checking the watch.

Another problem is the bright backlight lights up the whole watch face including the numerals, and without glasses it is not easy to distinguish the numerals. If only the numerals lighted up, they would be easier to see.

Also if you wake up before the alarm goes off and want to turn off the alarm, it is not easy to do so. First you have to switch to the alarm setting screen out of 6, then you have the choose the right alarm screen out of 6, then you have to be able to see the tiny alarm on symbol to see whether you turned it on or off, indistinguishable at night because of the bright backlight.

The watch is lightweight but bulky so it is not suitable for wearing everywhere.

I am returning it and going back to the cheap travel alarm clock that wakes me up reliably everytime.
