Product review (5 stars): Good tool
I bought this expecting it to be functional at best, and its actually really cool.  The rods are flexy enough to get where they need to (and around fairly tight bends) but stiff enough to not be like a wet noodle when your feeding it in.  It pulled piles of stuff out of my vents.  I've loaned it to a few people that have been super impressed with it as well.  Should be about $10 less, but you do get quite a few attachments so hard to complain i guess.
