I've had it for over a year.
Use it daily, and my son has his own copy on his iPod so he and DH can stay on top of their tasks.
I played with jigging and rejigging the morning/eve and focus zones.
I made a list of things that needed doing every day as I did them, then split them into "do BEFORE mumsnetting" which bacame the morning list, the rest went on the eve list, as in do before you fall over too tired to move.
I did one room at a time making a list of the jobs I always tend to do and the ones I tend to forget. Then put them in order of importance in terms of regularity, so if I don't always finish the list it's the non "end of the world if gets forgotten about sometimes" jobs.
Then fiddled with which zone number they were in until I had them set up so I didn't have mad days and thumb twiddling days.
Took me a while til I was happy with how I set it up, but once I was, just left it alone only to add new stuff as it cropped up.
