“This has to be one of the best Quality versions of this type of product. Whistling stopper is a great addition, but the product's packaging needs to be updated to reflect this as the box still carries warnings not to boil with stopper in place. I might modify mine to have a fixed side handle like the Thermette, the swinging handle is a bit silly, requiring a special technique to use and can be very dangerous for someone not used to this type of kettle.”
