The Remember Ring™ utilizes patent pending Hot Spot™ technology to deliver a reminder that it’s “That time of the year again!”
24 hours before your special day, the Hot Spot™ on the interior surface of your Remember Ring™ will warm to 120º F for approximately 10 seconds, and continue to warm up every hour, on the hour, all day long! Hot enough to cause discomfort but not hot enough to burn-the Remember Ring™ is impossible to ignore!

I like this. You shouldn’t forget any of your firend’s aniversary… but even if you do, this ring helps you to remember the dexact date. Trust me… you won’t forget any of your friend’s aiversary with this ring.
