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 an old Vitamix. Also great, but it took up too much counter space. I had one of the ‘bullets’ to save space. Waste of space and money! Love this one. Very satisfied. Sits out all the time and used almost every day. Don’t waste money on a cheaper deal. This works!

I already own the larger regular size Vitamix which I use when I cook. My husband has a Nutribullet for daily use to make smoothies. He is on his third Nutribullet in three years. The machines keep breaking just out of warranty. I convinced him to not buy another one but get this smaller Vitamix instead. The refurbished price tag made buying it an easier decision. So far it's been great. I'm taking smoothies to work in the to go container as well. The 20 oz. to go container is slightly problematic. The lid is bulky and the latch is pretty tight and hard to open. The 20 oz. to go container doesn't hold as much as the Nutribullet container so it has been an adjustment. Once I learned to put in the right mix of leafy greans, fruits, ice and water - it's been a dream. Make sure you add enough liquid.
