Query: Bang for the Buck

This kettle heats water in a matter of seconds and you absolutely can't beat the price. We have been using our 5-6 times a day for months without a single problem. My only two complaints are that you can see the plug spark when you unplug it. I have never had it do any more than that but it seems a little scary and there is no way to avoid it since there is not an on/off switch. The other thing is that the lip around the spout is oddly shaped and if you are not careful you wind up spilling a little water as you pour. The drawbacks are very minor in my opinion compared to the heating efficiency and the low price.
