Bought this to take with me to work. Works great!  Manage your expectations though, this isn't going to replace your plug in blender, this is for a quick on the go smoothie. It has the power to make smoothies no problem, but you have to get the ratio of fruit/veggies to liquid right. I use frozen fruit and juice, about half full of juice, and then add frozen fruit to the fill line on the cup, maybe a little less. I find the 30 sec cycle isn't quite enough, and will run 2-3 cycles. I also have to shake the contents a little bit while it's blending as sometimes an air pocket informed around the blade. Over all, I'm very happy with it. Is exactly what I was looking for.
