It doesn't work. Don't waste your money. Mine didn't break as the others stated. The blade isn't sharp enough to cut butter. I got one decent cut out of a full watermelon. I am a kitchen professional and was hoping to find an easier way to make even slices and cubes but you can forget using the Slice Right for that! I will be contacting the company for a refund.
Bottom Line: No, I would not recommend this to a friend
