I got a different brand's personal blender from last year's Secret Santa at work and I decided to exchange it for this. I love that this model has two sets of blender cups and two lids. I also love that it has two different blades, one for blending regular smoothies and one for grinding nuts or coffee. I have tried it so far with blending nuts, making smoothies from frozen fruits and from just fresh fruit and ice. I am surprised that it really does a great job. As long as you read and follow the user manual, I think this will last long. The one star less from five is due to the size of the cup which is too big for me but if you are a heavy smoothie drinker, this will work perfect for you.
