I bought this 3 months ago and I have pretty much used it everyday since with no issues. It is great to have the flexibility to use the larger and smaller sizes for smoothies for just myself or the entire family. We even used it to make a delicious tomato soup as well. No issues blending at all. So much better than any blender I’ve had in the past! The extract option is also a unique feature for blending smoothies or bowels.
