The multiple alarm feature on my SE W960i is really useful.
I can set up 3 separate alarms and each alarm can be given a name and can be set to ring in lots of different configurations such as specific days, daily, weekly or just work days.
I have setup my 3 alarms as follows 06:20 Workdays
07:30 Saturday
08:00 Sunday
I now have a ready made lie in on Sundays. Woo hoo
To make sure I actually get out of bed I have setup a phone charging point on the landing so now I have to get out of bed to stop the alarm.
