The nice thing here is that they appear to be using automotive grade components (it says -40 to 85°C operating range). I've previously designed electronics for extreme temperatures (up to 150C in our case) and building hardware that works at those temperatures is very tricky. It's nice that you can buy something off the shelf like this, my life about 10 years ago would have been so much easier had this existed.
