Could be better, but nice and simple design, get the job done. Use large amount of power 750W x 3 hrs for around 3 liter of water, that is around $1 for one jug, never try other brand so no idea if that is some that is more power saving.One thing I don't like is you can't add water in for continuous usage, you have to wait till it cool down and then open it to add water for another round. And it generate a lot of heat for as well, which is really good for winter, but not summer.
