I wanted a reasonably priced water heater that also provides nice functions. I was a little worried after reading the first review about the burn marks, but to my surprise it has gotten great reviews elsewhere, so I decided to give it a try.Funny that when I received the package I was deliberately looking out for signs of previous usage or burn marks. But it was brand new. Shiny stainless steel tank. Now it has worked perfectly for me for about a month, no any marks whatsoever. I feel it is a good idea to provide this review, so people don't just walk away from this nice water heater and possibly go for something more expensive but inferior.I did realize that there is a stainless steel exterior version of this heater and tend to be about 10-15 dollars more expensive than this one. But if you check the manufacturer's website, both versions are priced almost the same. So you are spending extra for the look.Other pros than the product description you can read above:--very well built--nice size tank--great easy to read instructions--energy saver features (save energy during night)--to me, it boils water fast, so fast I never realized the wait, but maybe it is due to that I don't always fill it to full--comparatively quietCons:--it can be a little shaky, because the base enables rotation towards any direction, which is supposed to be a nice feature if you have a kitchen island, but if you don't need to turn it from time to time, not so useful. But as long as you put it on really stable surface like kitchen counters, you are fine.Thanks for reading.
