Query: Terrible

I bought this based on the other reviews, but mine stopped working within six months of purchasing it. It needed constant cleaning of the part that wasn't removable, in addition to sharpening ... and no, I wasn't using it to cut steel or pouring syrup all over it - just opening cans. We ended up buying a replacement at a drug store for $8 that has worked exponentially better than this thing. I am quite comfortable saying that it is by far the worst appliance I have ever owned. Save your money.
