Query: Powerful, Quality Juice Extractor

This machine is not a flimsy plastic juicer that you worry about whether a carrot will break the mechanism. No, this thing is a power house. It sounds like an airplane taking off and takes a good while to stop once you turn it off.Very simple to use, fairly easy to clean, it does not make a mess. The juice strainer is very thick (high quality) and it seems built to last. It has no problem getting through fruit or vegetable I've thrown its way and the juice is great (good volume and no pulp gets through).
