To me, the bellows quality in its function. However When unpacking is one of those disgusting rubber smell counter (not the same as the smell of a new inner tube), so I put the part first to the air for 2 days on the terrace. It really is that the later also smell their hands after any plasticizers. Unfortunately, the smell from the bellows is not left after 2 days of it. In the desk drawer, the part is only once halfway isolated, I thought. But again, the stench will find its way to the nose. In the camera bag comes to me so not what.
This bellows really should not do that to yourself.
