Magnetic Lock For Better Home Security
By Alex M. Furlo

You can purchase a magnetic lock for about three hundred dollars while a more conventional lock can be bought for about forty dollars. It is possible for your magnetic lock to cost you money on your electric bill. If this is the case then be ready to pay about three dollars a year for each magnetic lock you use.
