Tupperware products are sold at almost twice the normal cost and are not only of inferior quality but get damaged easily. They sell it with Lifetime warranty but when you go exchange the same they have hundreds of flimsy reasons to reject it. All they are interested is to sell their over priced products giving false promises. For example they sold me tiffin boxes saying they can be used in microwave but when I used it and later found problems they told me that it is never supposed to be used in microwave for warming. Also the product started having stain marks within few months of using and when complained they told me that it is because of improper cleaning. I have been using several similar such products of other brands and never found any issues. In one work avoid their over priced inferior quality products; don't trust their life time warranty clause as it is filled with conditions and will never work in your favor. Final Verdict: Avoid and Never buy Tupperware products.
