great when you sleep alone!

it was invented!
The concept is great ... but with a margin of 30 minutes to wake up gently before the hour "H" and my husband got up 30 minutes before me (job oblige!), so, before I turned and fell asleep again more or less, and now I wake axbo systematically sounds 30 minutes before the hour!
Result: I returned to my old alarm clock (classic) and I go to bed earlier ... shame!
So well thought if sleeping alone or gets up at the same hour every 2!
