Just received my refurbished S30 and while I have not tried it yet (I'm sure it functions well enough), I have to say that Vitamix makes no effort to sell you a clean machine. The motor was filthy. There was residue beneath the motor where the feet are, the front was dusty and the top of the motor is very scratched. Had I known how filthy, dingy and banged up these refurbs are I would have shopped for something else. Makes me want to return this one and sell off my 750 too. Very disappointing.

I presently own a Vitamix Clasic C Series Blender and love it. I brought the S Series for a winter home based on my experience with the C Series and its compact size. What a disappointment. When using it on high speeds it vibrates so much it moves along the countertop. The cleanup it's not as easy as the C-Series. The container, the seal and blade have to be separated in order to clean. I notice an electrical burning odor when the motor is running on high for less than a minute. It does blend good. I would definitely buy another Vitamix, I just would not buy or recommend the S Series.

I already had the full sized Vitamin when I decided to get the little S30. The big one is on a shelf in the pantry because it is just too big for my counter. The little one is great because it can sit on the counter and I use it daily. It doesn't do everything the big one does - won't heat soup, and doesn't pulverize seeds. I love them both, and they both do a great job of certain foods. Once you have a Vitamin, you'll never buy another blender. They are built to last.
