Yes, they are amazing. It's one of those things that once you get one, you wonder how you ever lived without one.
Our microwave sits on top of our refrigerator, and it's really too high for me, but I rarely use it. I bought our electric tea pot to avoid dumping boiling water on myself. I had no idea I'd use this tea pot so much for other things!
For example, when we are boiling pasta I fill the tea pot up, put a little water in the pasta pot, and then dump in the boiling water from the tea pot into the pasta pot in about 2 minutes. Sure speeds that process up. I didn't say that very well, but what I'm trying to say is I use the tea pot to get a jump start on boiling the pasta water.
I use what's left over in the tea pot to clean out my foo-foo-hand-wash-only skillet from the breakfast scrambled eggs. Speeds that up too.
And whenever I have some hot water left over, I dump it down a sink - that helps melt away any icky goo forming down in there.
Thank me later.
