Product review (2 stars): You better not want your water hot
I bought one of these and I am very disappointed, I expect more from a high end system.  The chiller works adequately but the heated water is a joke.  I turned the heat all the way up and the best I can get is ~180 degree water.  After about 8-10 oz of water are dispensed the temp starts to drop and within seconds it is 160.  I consider the hot to be the primary function and chilled to be a nice add-on.  Unfortunately, 180 isn't hot enough to tea and surely isn't hot enough for coffee.  If I have to put the cup in the microwave after getting the hot I don't see the point.

I contacted the manufacturer and they tell me to insulate the tubing, check the voltage, and turn it up.  Seriously?  I am using one of their faucets, a dedicated circuit, and I am not completely stupid so I had already turned it up.  Other than that they had no suggestions.  On the plus side they did respond quickly.

Chilled comes out at 40 degrees and you can fill a glass without problems.  I haven't tested the cold capacity because it works well enough for a secondary function. Despite average instructions (missing some details like those below) installation was pretty easy and I would say that the overall build quality is good.

NOTE the hot out is 6 mm tubing and the rest are 1/4".  Also noteworthy is that they provide these 90 degree angle connectors.  The connectors are for 6mm tubing but they are plastic so you can't use them on the hot.  If you try to insert 1/4" the angles will not seal and you will be cleaning up a puddle.
