Have You Tried Deal Dash?

Have you heard about DealDash? It's one of those auction sites that are becoming popular.  On Deal Dash, you can bid on great products, and if you are lucky, you can score some good stuff for pretty cheap.  I have never used a site like DealDash before, but I am interested to hear from any of you that have.  Is it easy to use, and did you even win an auction? Let me know about your experiences, so I can decide if it is something I might try for myself.
