It works perfectly fine.
Yes, it's a bit awkward, the hose is stiff and sometimes the suction cups get loose.  I deal with it, because I like how it helps.  This vac is not meant to clean up all the hair everywhere.  It's for cleaning the hair that won't blow off with a hair dryer.  There's typically some small bits of hair around the neck and ears that doesn't come off with my blow dryer, and this takes it right off!  My routine, blow hair off, remove cape partially and shake off, replace cape, snap loosely & tuck under shirt in back, trim neck hair, blow off hair again with hair dryer, and then use this vac to remove the remainder of the hair.  That's what this vac is designed to do & why the collection cup is fairly small.
