It gets me up better than any other alarm Ive used. Once or twice Ive been stubborn and crawled right back to bed afterwards, but tens of other times spinning (just twice) has waken me just enough to do the trick.
Biggest wish is that they add better alarm sounds. Sleep Cycle has some great ones. They should emulate those.
