Well I tell you straight up good, bad, or indifferent. The machine is not as quiet as you advertise. Matter of fact it is loud. Once you are ready to blend make sure you don’t go above the fill line. After you make your drink it’s very hard to to remove the screw on top. One time I guess it wasn’t meshed with the gear on the machine and the mixture went everywhere. Then I had a difficult time getting the black screw on top with the blades from the machine. You should let me test your products and get a hands on review.
