Conservative estimates are that the average man will lose 12,547 umbrellas during his lifetime.
Despite being quite large and oddly shaped, umbrellas top the list of easiest things to lose in life. Somehow, these useful defenders against the nefarious forces of rain, sleet and hail, always seem to seek out small crannies between cinema chairs, underneath train seats, or in covered nooks in cafe corners, where they can become immediately forgotten.
So, all hail the $117 Kisha Umbrella. The world's first "smart" umbrella (according to the sales blurb), the Kisha gives you a heads-up when rain is in the air, and provides a gentle elbow in the ribs when you leave it behind.
Thanks to an integrated Bluetooth contact with your mobile, all you have to do is stray 30m away from your brolly and the phone will buzz in alarm, before displaying a map of the item's whereabouts.
