Query: Do NOT buy this kettle!!!

They changed the Uplift kettle, and the newer generation is definitely inferior to the previous. The kettle no longer features the pleasant harmonic whistle. The stainless kettles also have a seam along the bottom that the colored kettles do not have. It distorts the aesthetics. And the brushed stainless model takes FOREVER to boil.
