Absolutely love this kettle! Really cool! Love a glass kettle and the blue lights make it look great! Looks really smart 
I have hard water so get a lot of lime scale  so hoping this will help with that, so far so good! 
Only issue is the filter means that you can only slightly fill the kettle each time, as you need to let the water drain though, maybe the filter could of been placed lower so that the kettle can be filled more … 
So a tad annoying when you want to make more than 2 small cups but otherwise fab!
