Pros: Quick hot water, handy cordless design.
Cons: Small opening on top, a little dificult to fill
I bought this unit to make tea. I then discovered that it is excellent for making intant soups that just require you to add hot water. I wish the top was a little bigger so I could cook eggs in it. Alas, I'll have to purchase a different model to allow me to do this or I'll just stick with the sauce pan on the stove.
As far as the stale smells that I've read in other reviews, here is my suggestion: I have been using ONLY filtered water (such as Brita) for many years in my coffee/espresso makers and in this unit also. I have never experienced any unpleasant smell from the unit at all. Other reviewers have probably never noticed a stale smell from other hot water devices because the coffee aroma is much more noticeable.
I do agree that the outside of the unit tends to get pretty hot, but I live alone and have always been careful about the placement of any appliance like this. It's only common sense. I have measured the outside temperature of the unit using my laser thermometer and have never seen it read higher than 140 degrees F.
