Excellent product. We immedistely noticed this cup is no ss noisy as the clear ones. Since we use the Vitamix to prepare warm food to tube feed my daughter three or more times a day he time to get her food and supplements to blend and warm, everyone noticed how quickly this cup does the job--about half the time. We also noticed that vitamin pills no longer are found stuck on the blades instead of blending. We are very happy with this ourchase.It is also outstanding with smoothies snd even ice cream.
