Co-Gain Magnetic Master RT

You know, I'm not even mad these don't have real names, the serial numbers are fine. So we finally found the manufacturer of these weird opticals, Co-Gain/Xuda, and even found a website and taobao storefront. So of course I had to buy all their OEM level stuff. These ones are actually a magnetic switch largely reusing the optical molds which is neat. They don't even get a serial number though which is sad.
