Electrical jolts caused by static electricity. I think everyone has this trouble with their cars. In my case it happens all the time when I get off from the car and I touch the metallic part of the door. Practically, our body is charged with electrons and when we contact a positively charged material (like a car door) the effect is a static shock.

The device called the Static Electricity Eliminator (or SEE) is able to protect you from unwanted shocks. It fits very well with your keyring, and anytime you need to discharge just touch the rubber part tip to a grounded object (a metal desk leg, your car door, etc.).

The Static Electricity Eliminator retails for only $10, but temporary is out of stock. It doesn’t require batteries because you are the source of energy.
