User Review: Update:  My Kettle finally gave up the ghost on July 16, 2012, after 11 years & 3 months of faithful service.  I found the ON button had snapped off during the night.  I could still technically get it to turn on, if I stuck a fork in the hole, but it was time to give it up.  Too bad I had to throw it out over a piece of plastic that can't be replaced or fixed.

9/24/11 Update:  My kettle how now lasted me 10.5 years!  So I'm upgrading my review to 5 stars.

This is my first Amazon review.  I'm not usually inclined to write reviews, but I happened to be going through my old purchases here on Amazon to find something and I noticed that I purchased the Cuisinart Electric Kettle from Amazon in April of 2001.  It's still working great after all this time so I was inspired to write a review. To wit:

Aside from time spent traveling, I have used this kettle almost daily since the moment it arrived in the mail.  That's 9 years ago and it's still going strong!

Pros:

**I love that the kettle comes away from the base so you don't have to worry about a cord tangling up.  Also, the cord winds up underneath the base so it's not in the way.

** The water heats up quickly and it shuts off automatically so you can turn it on and forget it.

** No annoying whistle to wake up your sleeping household first thing in the morning.  The button makes a pleasant sound when it "pops" to tell tell you that the water is ready.

**It's very attractive to have as an item that lives on the counter.

**The outside is easy to clean and and keeps it's shine after all these years.

Cons:  Minor Annoyances)

** It's very easy to accidentally hit the ON button, either with your fingers or say, a bag of chips or something else on the counter because the button sticks out from the base and only takes a few ounces of pressure to push down.

** It's almost impossible to get all of the water out of the spout without having to practically turn it upside down.

** Can be a bit tricky to clean the inside because the "max fill" plastic piece that sticks out inside the pot.  Once a year I boil a 50/50 mix of vinegar & water in there to clean up the eventual build up and I have to use the end of a wooden spoon to move a paper towel or scrubby inside to get what's left.

Note to those who are considering purchasing this item -- I have seen a whole bunch of reviews here that say the kettle gives up after 1-2 years, so I maybe I just got very lucky?

+4 Stars for the "pros"
-1 Star for the "cons"
+1 Star for lasting 9 years!
