If you have expensive electronic devices in your home, such as a big screen TV, a high end computer or anything else that you have invested a large sum of money into, you surely don’t want it to take damage from something as unpredictable as a lightning storm.

For a pretty low cost, you can invest in a surge protector to prevent this from happening. Many surge protectors will come with a warranty for a certain amount of electronic equipment plugged into it. Of course, the reliability of the warranty depends very much on the company that makes the surge protector. You might want to do some research before buying.

Your surge protector is only going to work for a few surges, so it is wise to replace it after a few years, especially if you live in an area where power spikes are common. Usually the protector will have a light indicating whether it is working properly.
