I bought this swab to clean my new Jupiter JBS1000 bari sax. It works great!
The fabric is very soft, which makes it seem impossible to get stuck inside. This is different from the cheaper swabs you can buy. The little weight on one of the two ends is quite heavy, for me it was no problem getting it through the baritone saxophone, despite my initial fears.
I would recommend this swab to anyone with a baritone saxophone.
