the fastest and perfect for induction cooker!

had different kettle and let my old Philips kettle compete against each other. Kela took one liter of water 20 seconds faster on my induction stove to cook, as the kettle. He was also faster than a boiler of WMF and two other volunteers.
also has the Kela the largest capacity when things need a little more boiling water.
improvement I find only two points:
1. The cover insert should be tight, because when cooking there quite a lot of water / steam escapes
2. the opening lever should be fitted for a more ergonomic pour out more at the handle end
