Really wakes you up!, 5 Nov 2012
Does exactly what it says on the tine - wakes you up without feeling groggy or grumpy, providing that you have had somewhere near the sufficient level of sleep you need. It won't work miracles!! I have noticed my partner - who is very lazy in the mornings - has started sleeping through it. But to be honest I put that down to sheer pig-headedness.
Worth the investment.
