Product review (4 stars): Great for slow cooker Sous Vide
This is just a wonderful little PID.  It took a little reading on the internet, to find a wiring diagram but once I did wiring it was easy.  This is the main reason it only got 4 stars.  The instructions tell you to only wire it the way it was shown, but dose not show you how to. This is a great unit for homemade Sous Vide machine, primarily because it's cheap but also it remember's your settings, so you do not have to set it every time you plug it in.
