I've got one. It is great for Apfelwein, would be good for regular wine. For beer it is not so good if you have lots of trub/cold break, etc. For yeast harvesters it is pretty cool to use but I no longer bother with that.
I have mine mounted on a handtruck so I can wheel it around, when transferring to keg I lift it up to a higher set of hooks that I installed on top of the handtruck, all this works great.
I also have a 15 gallon Inductor tank from Tank Depot (HBT member) which I mounted on a rolling stand that I made from spare parts. This works much better than the VV for beer.
