I purchased this kettle because it is glass and filters the water so meets all my requirements.
The switch broke after about 18 months but with the 2 year extended warranty it was replaced no questions.
I was only offered the remaining warranty on the new product which seems rather short sighted.
Both kettles leaked from the base extensively so I was pleased to get a new one. I have recently received replacement kettle number 3 due to excessive leaking onto the electrical base plate.
Sadly after 10 days the new kettle leaks just as much if not  more than the old one.
They have offered me a 4th replacement but I think I will move on from the brand and look elsewhere.
