I have that same kettle, it’s so simple but great.
Could’ve fooled me. I got mine for the temperature control and the goose neck spout. Going strong for 3-4 years now.
Only annoying part of it is the flow control is just a little too aggressive. I have to break out my other kettle when i’m making tea because I just can’t quite pour fast enough. But ya there’s only a few kettles that you could argue are actually better than the stagg. And sure you pay a bit extra for the design but that’s fine.
I’ve read that many others have had QC issues, but it’s worked a treat for me.
