The Remember Ring

Bad Scenario # 1: Tired of reminding family / friends / your worse half about important dates, appointments, and events?
Worse Scenario # 2: You are absent-minded yourself, and need to be whacked on the head to remember trifles (and have long run out of knotted handkerchiefs)?
Well, help is at hand with the Remember Ring, which uses a Hot Spot technology to ensure that you never ignore that reminder.
Available in 14carat white and yellow gold, these neat remember rings have a life-time warranty, and you can set reminders for those dates you wouldn’t want to forget.
The tiny microchips will start heating the inside of the rings, causing you some discomfort, on the day you set your reminder. They would increase in intensity every hour.
Before glaring and calling me names to the tune of a sadist-in-the-making, let me add that it's not that the ring would bake you; you wouldn’t get burnt or anything, but oh yes, the heat would definitely get your attention.
Quite a nifty thingie this – I’d love to get my hands on one of these.
Except that the problem is that this is a concept product, and no jeweler stocks it.
Hell – wish Tiffany’s / Cartier / Bvlgari think of making these soon.
Now if only I could also get someone to buy it for me...
