Query: Good design - Does not last

I bought one of these 4 years ago. It's a nice enough kettle - I had no trouble with the handles getting too hot or anything, and I like the 1-piece construction of the body (I've had kettles come apart t the seams before) but it started to deteriorate after 2 years. Call me old-fashioned, but a teakettle should last 20+ years if not abused.The spout and whistle-cap mechanism are not as well-constructed as the body of the kettle. The spout began to get loose and the cap started wobbling after about 2 years of use - it became tricky to get the cap to sit right (and if not, no whistle)About a month ago, the mechanism stopped being able to hold the cap open - now it won't stop whistling unless I prop the spout open with something.I'm buying something else this time**FYI - after reading the reviews here I also wonder about the metal content of this item - particularly the spout (one reviewer says it's aluminum, but I think mine is rusting)
