My husband purchased this blender set for my birthday a few years ago. I was extremely excited to use it to make smoothies and milkshakes. The first few uses was great! It blended well and seemed powerful. Shortly after I noticed the power wasn't as great as it once was, and also that it took 10 minutes or longer to break up ice completely. Even then I was still left with huge chunks of ice in my smoothies and milkshakes! This product is just not for me!
