Second time buying. Just one hit the first time. The teenagers tripped over some nails and they were punctured and needed replacing. This time I opted for a package with an extra as it wasn't much more expensive. They are a bit longer than necessary, so I had to shorten them a bit. They're tricky to install, but I think that's mainly due to the construction of the vacuum cleaner. I love Shark vacuums, but they don't provide repair documentation and sell not just that hose, but the entire brush assembly for about $70. I figured out how to take it apart but it's very difficult to put back together. As a result I had to solder the wires as they broke.
