I love how fast this kettle heats up, but the inside looks discolored on the bottom. I’m not sure if it’s rust or what.I took 1.5 stars off for this. I also deducted another 2.5 stars for not refunding my account after I returned one of the two kettles I ordered. I ended up filing a claim with my credit card company. They gave me a courtesy credit while trying to pursue kitchen aid for the balance. It’s been four months, and they still  haven’t issued the credit. I’m thankful my credit card company provided this service.
