Some random NXR information
Randomly, I found the actual manufacturer of the NXR ranges. The company is called Hyxion Metal Industry. They have a pretty detailed web page (in English).
They also have an Alibaba page where you can order their ranges (in bulk) and even put your own logo on it. (like NXR)
Here are some interesting pictures I found too:
Factory Assembly Line:
48 Inch Range:
Customizable shipping boxes:
Some the most interesting tidbits of information I read are:
Their manufacturing machines are from Japan.
Some of the range parts are from Germany, Italy and USA. (we already know this)
They have passed various US and Canada CSA and ISO certifications.
Main customers are Costco, Lowes, and Best Buy.
