For those of you who can’t remember a birthday to save their life, this ring will help burn it into your memory.

Whenever you set the date, the ring will “heat up” to 120 degrees Fahrenheit 24 hours ahead of time all day for 10 seconds. Supposedly the ring heats up enough to “cause discomfort”, but doesn’t burn you. Cool thing though that it uses your body heat to recharge the ring.
