Query: Did not wear well.

I received my new juicer blade in mid April. I juice daily so, I put it to work the next day. I juice the usual things, carrots, beets, apples, greens. Nothing dense or hard. My new blade started to wear down on the outside teeth by the beginning of May. Not quite 3 weeks. I contacted the seller and he agreed to either replace it or refund my money so I returned it and am waiting for a refund. It must have been a lemon. No blade wears that quickly. Seller said he gets them directly from Acme. I chose not to try it again. Thinking of getting a new juicer instead.
