I purchased this item in white.  Very sleek and neat. The average size is 1.7 which is larger and rounder. I had to return a few because they were to round in width.  This size is perfect.  You can make 4 full cups of tea at one time.  Lightweight. To add water just place under faucet “THEN” turn on faucet over lid (you DO NOT HAVE TO OPEN OR REMOVE LID) fill to marker and place back on swivel. PLEASE MAKE SURE IT’S DRY BEFORE DOING SO!  I kid you not in less that 10 seconds the water begins to heat.  What I ❤️❤️❤️❤️❤️ about this when you switch it on to boil it will automatically shut off when it gets boiling hot.    Yes I’m a satisfied customer.
