Query: Not Quite 5 Stars.......

First, I got the machine cheaper ($500) with free shipping directly from the manufacturer. I'm not sure whether or not this was a special. As for cleaning, this machine is about as good as it gets. The Infomercial is a bit of a stretch and a bit misleading, at the same time, it is still a great machine. The only problem is that the tank is too small, and I'm sorry I didn't get the wider machine. I cannot count the number of times I have to fill the tank. There are some good hints about using the machine submitted by others here, and I would like to add one more. I crank up my water heater to high before using the machine. Just be careful so that you do not burn yourself and don't forget to turn the water heater back down when you are finished.
