SinnoRally TEM cell SR_TEM_CL002

[dexar]

Happened by accident to stumble over a cheap TEM cell on aliexpress:

It seems to be made of 3d printed parts. Note that the company name that is printed on it is "SinoRally" but the store is called "SinnoRally" with two n.
This makes me wonder how good it is but at a price of $260 it is sure tempting.

Has anybody tried it or seen it in the wild?
