Thats the 1201, the 1211 uses a different brand of spectro.
Not sure what you were expecting JimP, the simplest form of spectro you can make yourself with a CD/DVD and cardboard box. But making it work and report real data takes a little more skill.
just google Spectro design, actually the jeti site has good data in general.
