Query: Questionable Value

Clearly a professional would not purchase this 'professional quality' mandoline. Four pieces of plastic and 3 blades. No stand. Julienne blade was miscut and 3 tines bent back on first use. Small thumbscrews not for arthritis. No storage space for extra blade. Poor documentation on use - in particular no instructions on techniques to use safely. I can't understand prior high ratings.
