Nothing to watch the naked eye we see the poor quality of the product. The edges of the plastic pieces are irregular and not trimmed, labels take off ... At the first use after installation of new batteries, you can not turn on the mixer. The battery is such that they "descend" and are no longer in contact with the pads. It took the stall with paper so they do not move. I am very disappointed and I would not give much for the life of this product even if I was very careful.
