Several design flaws. Unless you are using a large pitcher, tall enough to be right under the juice,r be prepared for a big mess. This could have been solved by a) having a larger grid to contain the pulp, b) designing the body of the juice extractor in such a manner that the spout could be closer to a smaller pitcher or container. It seems to have been conceived for individuals with 3 hands: one to hold the fruit, one to hold a glass and one to hold the stand mixer so that it does no go backwards when you are pressing your citrus... 
A horizontal (instead of vertical) juicer would have been certainly a better, albeit more expensive, and less messy idea. (This review was collected as part of a promotion.)
