I bought the Sat-Nag as a wedding anniversary present for my husband (never let it be said that romance has died!) and truth to tell I wasn't too sure how it would be received.
I needn't have worried: he and our friends have loved the spot on comments made by the Sat-Nag and have marvelled at just how well the voice seems to know our conversations!
I absolutely recommend this device and have several friends who have said "I want one of those!"
