My son gave me a Kitchen Aid bowl-lift Stand Mixer a few year ago and I really like it, however the enamel on the flat beater is chipping off.  I’ve only used it maybe 20 times and feel that it must be defective.  The enamel is bubbling on the other side also.  I have never put it in the dishwasher and was always careful with it.  I no longer want to use it as I’m afraid that the enamel will drop into the food and I don’t want to poison anyone.  I was very  disappointed when my husband notice the chips while he was washing it.
