It works very well, although I would make it a little easier to turn off (currently you need to press three buttons at the same time) and it would work better for my uses if the 5 minute and 10 minute warnings would automatically turn off like some of the other times I have used in the past.

So now I set the alarm ahead around 20 minutes so it will alarm around the right time

but currently we have no other options and cannot find anything currently better than this thank you Shutting off the alarm you have to hold the key button and simultaneously push the hour and minute buttons, remember the alarm will go off 10 minutes than five minutes prior to the alarm hour, pre-alarm cannot be shut off but when it sounds you just press the key button once sleep feature and in five minutes press the key button again and then to shut the final alarm off again

The pre-alarm goes off 10 and 5 minutes before the real alarm

This futility lasts no more than 5 minutes before the Meanie wakens me once and for all because it cannot be silenced

a bit confusing 4 a minute but wks good

Very loud will scare u
