The one that I have is very efficient - but every time I want to set
it, for example to be off for a week away, and come back on the day we
return, I have to get the instruction manual out and spend a fair bit
of time fiddling with it.

I have one that also requires me to dig out the manual when I want to
change it. Not only is setting the device non-intuitive but the manual
is poorly written.
