Just a little update.
The box in the outside says
"Suitable for following models:
Rode NTG1, NTG2, NTG3, NTG4+
NEUMANN KMR81i, SANKEN CS-2
SCHOEPS CMIT 5U
SENNHEISER MKE 600, MKH 416"
My guess is that Rycote is right, this is suitable for the aforementioned mics!
The choice of colors make it a bit more desirable in style, it does seem like a cheaper version of a proper windshield, and I do not think it does such a good job, but for the price, and most jobs, I believe it is sufficient. I enjoy and like it more than the Rode one, no question about it, but it isn't cheaper than the Rode (here in Europe at least), but then, it is almost half price of the other Rycotes.
I tried to fit my Audix, its diameter is 21mm and it seemed like it could open permanently the Lyres (which again, seem like a cheaper version from harder plastic than the original ones), but it could be possible to fit it there (there are some options of where to put the lyres, but just a few) if a back pod was added at the front, and maybe add the windjammer from the WS10, or something, but that takes a lot of extras (the pod only is something around 50-55euros).
My interest lies to the fact that the Sanken CS-M1 has the same length as the Audix, but it is 19mm in diameter (so, fits exactly and with no violence the Super shield's Lyres), so maybe a mod of this design is appropriate for the budget conscious (the Cosi and the WS10 cost around 550euros, with the Cosi having many advantages, but one significant disadvantage, can't take the fur out, or anything at all, for when going inside).
In general, I am happy with my purchase, it is going to be my backup/B/lower budgeted jobs blimp and it certainly does the job, while it is a bit smaller (both in diameter and length) than my Sennheiser one, so it could fit easily my K-Tek BLT35 bag for those endeavors that need a light setup!
