A wonderfully quiet fast  boil. Aesthetically stable design. Soft colour to contrast my toaster and kitchen.  
Variable temperature range with a futuristic dial and an ascending scale of boil. 
After all that,  I simply love my new kettle ❤️ And would highly recommend all Kitchenaid products not the cheapest for sure, but simply the best. You get what you pay for at the end of the day
