  • Excellent upgrade from older tech

    This is great, exactly replaced former unit. The old unit was impossible to program, small print, ridiculous manual, very confusing instructions. Complicated series of buttons to push and menus to figure out. This was simple and works fabulously. WiFi to my ipad, program in bed, so simple. Wonderful upgrade.

  • Easy install, easy to setup

    This is a great product. Easy install and setup. Love the power usage data history!!
    A little spendy, but with the program and usage data, it could pay for itself by reducing electrical bill. Love the fact I can monitor and change setting when away.
