CLEVELAND, OH — If you have a doorbell at your home or office that hasn't evolved since 1970, today one upgrade is the absolute best tech deal in the country.

It used to be that to have a doorbell installed, you needed to buy a doorbell and multiple buttons at a hardware store, hire an electrician and fish the wiring through the walls to connect the system.

Not only was this inconvenient, it was also expensive, costing at least $300. Over the years, there have been different versions of wireless doorbells designed to be convenient and plug-and-play. The problem was, they were usually expensive and many were not waterproof or dustproof and often failed. That all changes today.
