Its gone freaking stupid.
And this little guy was the funnest two bucks ever, only needed a new valve and a new generator
It makes a freaking mean pot of macaroni though...
I have the 533, which I suppose is the big brother of the 400. I bought it 15 years ago I guess. It's a heck of a unit. Little cold nature, but not terrible. I have had it apart a few times to clean it, but there has really been nothing to clean out of it. Even the little O ring for the fill neck is good to go. Just have to oil the plunger up every once in a while. If I don't do that, it's loud as heck and wakes everyone up!
