Bottom line, I've always hated sales folk. Especially the door to door variety. They not only weren't forthcoming with their intentions (came across as more of a cleaning service). Bottom line, that's how they get in your house. Their "20 min spiel" ended up thing nearly 3 hours of basically them being extremely aggressive in attempting to sell their product... all while I'm watching my son right when he got home from school. I repeatedly told them "it's not happening, let's wrap this up. Now." Well, they finally left after repeated attempts of trying to get me into a contract (don't worry, it didn't happen). The kicker was that after they left, I discovered that with my Dyson, they turned it to "wood floor mode" while vacuuming before they showed what theirs would do basically meaning that the carpet didn't really get vacuumed at all since the rotor wasn't moving the entire time. Professional scam artists.
I didn't like: Pushy sales.
