I purchased this from a website overseas about two years ago. It's in beautiful condition as I've hardly used it. The last image is a current model from Rakuten, which is probably the same type. Size is Medium-Large. It's adjustable with a dial and suitable for standard adult men. There's no significant damage or noticeable odor. It comes with a storage bag and unused replacement pads. It fits in a backpack, making it very convenient. There's information on the website, and I believe it's a trustworthy brand.
