For product: It is very robust, ground very clean and I highly recommend it, it fits on and my camera (hot shoe and tripod socket 1/4 ") and the very precise.
To wear I can currently say anything because I have mounted on it today-only a couple of times now and, but the paint is well-adherent and does not flake, and the thread is cut very precisely, so that it does not wobble and holds.
The service from March barley is very very very friendly and on request you can get an immediate answer, I would not hesitate to buy it again in March barley, the quality is good, the price is right and the shipping is very fast.
Thank you for that, and in addition still: the hot shoe attachment is exactly 21mm x 18,6mm and 1,95mm thick, the adjusting nut is 20mm in diameter (4mm thick) and the thread is just 15mm long.
Fits perfect for Nikon hotshoe (and thus also determines all others) and 1/4 "threaded with my Nikon and the Zeiss 10x50 and the small 10-70x70 Sakura binoculars (are almost all cams and Fernfläser / spotting scopes same standardized)
