I have a family member with major health problems associated with his digestive system. We were thinking smoothies would be a good way to give him the nutrition he needs, so I started shopping.

I noticed previous reviews complained about how loud it is, but for the product you get, one minute of intermittent noise is easily tolerated. I also purchased additional tumblers See full review
