Query: Rust!

I'd almost decided that after testing half a dozen electric kettles, the Breville SK500XL Ikon was the one. It looked top quality and I loved the blue light that illuminates the water level. And although the water boil auto shut-off takes about 7-10 seconds too long to do its thing, I could live with that. It's also about 20% larger than need be, taking up too much space on the counter. Again, I could live with this. But what I can't live with is the rust forming at the bottom of the kettle. After just a week, I noticed there's rust forming where the bottom of the pot meets the sides. Apparently the seam isn't stainless steel or water has leaked below, causing rust on the underside which must not be stainless steel. Regardless, this is unacceptable. Breville needs to check this design because it's flawed if this is what happens when things aren't 100% properly welded.Returning to Amazon, and the search continues.
