Review on Efficient Deep Cleaning with Shark HVFH320: Flexible and Extended Reach by Wendy Smith

Like many others who have bought this, I find this extension pointless. It's too short and doesn't stay stretched, so I don't hurt my back trying to use it. I ended up adding another generic extension to this. This is a really good adapter as my usual one doesn't fit my shark directly and also fits this one which snaps into my vacuum cleaner.
