Query: unusable after only 6 months

I normally don't write reviews for products on Amazon, but this one was bad enough that I want to make sure no one else suffers the same.I bought this set in Aug 2009 and used them occasionally, around twice a week, primarily the saucepans. After a few months, I noticed some chipping of the teflon coating. This was very surprising given how little I used them, and how I always used soft utensils while cooking. As of last week, Mar 2010, I had to throw the entire set away since these "chips" have become huge tears in the teflon up to 1-inch in diameter that reveal the aluminum underneath.I only purchased this set because I had good experience with Mirro products in the past, and ironically, the one saucepan I have left from that last (good) set still has its teflon coating intact. Mirro product quality must have gone through some significant drop since then.DO NOT purchase this product!
