Being a bit of an equipment geek, I had to try out the new OXO mandolin. Well, I can safely say this is by far the best mandolin (at least for non-professionals) in the market.
It has a great rubberized feel, really easy to clean, and has a wonderful wheel to set the various cuts. I had tried the Berliner (didn't like) and Zyliss which was OK, but cumbersome.
This one is perfect. At around $55 is a steal.
