Product review (5 stars): That extra foot makes a big difference
I have a cheap washer with a 1" output. The standard hose that came with the machine was long enough to make it to the drain pipe but short enough that, once it started to fill with water, that the weight of the water in the pipe would make it shift just enough make it fly out of the drain pipe and create a giant mess. The extra foot makes all the difference in the world.

This has a graduated multi-size rubber neck that you can easily trim with scissors to fit your output size. Just try it on, trim, try it on again, until you get a good fit. Mine was the smallest size. Gives a snug fit and clamps securely with included crew clamp. The whole swap took about two minutes, and now I don't have to stand there like a sucker holding the discharge hose while the machine drains.
