Installed them on my ChaoYang H-5176 tire but haven't used it yet. Hopefully I'll remember to update the review with some real-life use (it's not winter here yet). The stud body is made of aluminium, so they're very lightweight. Both the body and the pin look like those on pictures, except that the tip is not that sharp (but it's a cone anyway, not a round tip). I ordered 150 studs and there were 160 of them in the package, which is good.
Everything is great. Thanks to the seller
