Query: Boils without whistle

I purchased this kettle because it was more expensive than another unit that was reviewed poorly for not whistling when the water came to a boil. However, this unit appears to have the same flaw.The lid/button linkage seems to be poorly designed - the lid never closes completely, therefore steam escapes without blowing thru the whistle hole. I fiddled with pulling the red button up and pressing the lid down, but other than a constant firm pressure holding the lid down, the lids not going to close tight enough to work correctly.Stainless, yes. Tea kettle, sure. Whistle, no way.
