This portable blender works great! I was actually surprised at how quickly and smoothly it was able to blend up all of the ingredients for my favorite smoothie! I like to put frozen fruits inside my smoothies and I was worried since the blades look so small that it wouldn’t be able to crush them but it did it with ease! And I love that you can drink directly from the top. It makes it so convenient to bring for on the go drinks! Love this little blender!
