I LOVE my E2 gold, but my E2 black is a better machine in just about every respect, if you can believe it! It doesn't have that shrill sound that sets off my tinnitus, and its generally quieter, noticeably more powerful, I LOVE the wands and being able to use the Rainbowmate on them. I had serious doubts about the PN design at first, but when they changed to the permanent belt off to the side, it helped, and then using it erased all remaining doubts about those spinny brushes on the side. I love the new 4qt tub too, much better design than what came before it. And I love the hose being a foot longer, and the trigger lock on the handle. I also love the lights that shine into the water, as I love watching all that action, and they help you see when you need to change the water. The only thing better than getting one of these is getting a good deal on it when you do!
