I got this to use the "New Style" upholstery brush with my DC07. Works perfectly. Other reviews mentioned things like "it's weak". It seems solid enough to me though, I could see that if you put it in the accessory hose and take it out all day, you might be able to pull it out and break it (eventually). My advice for this is to spray that end with some silicone grease (let dry/set before use) and it will slide in (but not out) with no problem.
