I can't stress enough how incredibly tolerable these things are. They attach to my Dyson which I bought on Amazon 2nd hand with no addons. They are an absolute must, they fit my slightly dented Dyson V6 which I bought new too cheaply - and yes considering I have a used and somewhat dated Dyson with fake tooling I might not know what I'm getting is not enough. to have the newest, best and most modern. But it's certainly better than my filthy devil, I tell you.
