Good product that arrived on time

SKH (Watkins, US)
Replaced a more complicated controller

This controller is great and simple. Would be nice if temps weren't preset but I can live with it. Was half the price of the one that quit but the old one also had several modes and outputs which I no longer needed. Supply Stop support is great!
