Works exactly as advertised so far
5/5
I've only been using it a week, but so far it does what it's supposed to.
The various temperatures are handy for coffee and different types of tea, and the temperatures lighting up in turn act as a progress bar.
The double-walled insulation and "keep warm" function are very useful when I'm cooking and might need boiling water quickly. The metal top section does still get hot; not as bad as a single-walled metal kettle, but I still wouldn't want to lean against that bit for too long.
A few other reviewers have mentioned that their lid mechanism developed a fault after several weeks or months. If that happens to mine, I'm reassured by Bosch's 2-year manufacturer warranty.
