Couldn't be happier with this system - it's compact, was easy to set up, hot water is instant and both hot and cold come out the perfect temperature. It's exactly what we needed in our office.
We are replacing the machine we already had due to a malfunction that wasn't able to be fixed. The water froze SOLID, and we contacted CS and defrosted it, only for it to happen right away again. So, he said it wasn't able to be fixed. We had to buy a new machine. :(
