after buying many Tupperware pieces quite some time ago, I have looked at all my Tupperware pieces only to realise, what a rip off it was to spend so much money on it. most of the pieces have worn really badly with peeling of the plastic or melting in spots an the so called microwave safe containers. I could have replaced each piece many times over for what I paid for it. I just sent in a claim to Tupperware for the damaged pieces and out of 5 pieces, one was approved!!!! don't waste your hard earned money. you can always replace a cheaper set if something is damaged. life time guarantee my ***
