I have the device completely satisfied for some time now and am. Since the smoothies are mixed directly in the bottle they are super fast finish. Prima when it has as I am in a hurry. The bottle is sealed and you can take safely, the blender is powerful, I've mixed all smoothies under a minute. Even with frozen fruit, the device can handle easily. I also like the look of the mixer and bottle, both looks great in the kitchen and can be accommodated without difficulty because of the compact size. I can wholeheartedly recommend the device to date.
