Part 3. Exercise
I've had one house guest and one nanny place this kettle on my gas stove believing it's a standard kettle. The first time, I wrote Cuisinart a letter, and they graciously sent me a new kettle. Great customer service. The second time, I'm going with a less confusing design, the Capresso glass electric kettle for a couple extra bucks. It's not worth burning my house down ; ).This design looks just like Cusinart's other standard kettles. So if you have elderly parents, or people what are not familiar with recent developments in water boiling, you might want to consider a less confusing design. (p.s. the plastic base melts in seconds if it comes in contact with a heat source).
Answer:
Negative
