I have used this wee blender to make smoothies for almost a week now. Despite its size, it's very powerful and makes a smoothie as good as my old-style big clunky blender. I love how easy it is to clean and the simplicity of it. A great price for a dedicated smoothie blender.
One thing to watch out for is that the bottle screws into the base in the same direction as how the blade/lid is screwed onto the bottle. Be sure to tighten the lid well before locking it into place, then unlock the bottle with your hand at the base of the bottle. My first attempt saw the blade/lid stay put, and the bottle (full of smoothie) unscrew! Since I got the proper technique down, it's worked like a charm.
Delivery from Smiths City was fast and the process was easy.
