The expectations I had when I ordered the product were exceeded when I finally received it (Canadian customs sat on it for 2 weeks!). Everything needed is included and the build quality is amazing. I bought a plastic case at a local shop and using the VERY well documented dimensions, was able to make the necessary panel cutouts easily. I added a 120V duplex (with careful consideration for isolating two sections from each other) in the same box so I could plug my toaster oven in there. However, with the included heatsink, the included SSR had to go outside the box, though I may change that given since the SSR doesn't heat up much (if at all).
The documentation for tuning the controller to any oven is fantastic though I chose to use the default leaded profile for my first board. It worked flawlessly! With the temperature profile graph, buzzer and excellent UI, it was a joy to use. It was obvious on the display that my cheap (Black & Decker) oven did not have a good heating rate for the final "push" since it only has a single element top and bottom.
I can't stress enough how well this product is designed and built, and how easy it is to use. I highly recommend it. Having a complete boxed unit is the only suggestion I can make.
