Logitech’s sleek design and rich features could make it the iPhone of universal remote controls! The Harmony One replaces up to 15 remotes and works with old and new technology such as HDTVs or old DVD players. It’s on board database allows you to control over 225,000 different devices and Logitech updates the database to ensure your universal remote control keeps up with technology. Setup is done via the internet using a web based setup guide. I had no problems with setup; just attached it to my PC and picked my devices.
