The Nutribullet blender combo was purchased in June 2021 and has worked beautifully. Was interested in a product that would occupy the least amount of space on the countertop but had the ability to create a single serving as well as several servings at one time. It has been trouble free, and it has been used to create on average five smoothies a week since being purchased. For the money, it is the best investment and if it stopped working tonight, I would be purchasing a duplicate machine tomorrow.
