This unit has exceeded my expectations. My family loves the taste of the water, and we use it for everything. I had read the reviews before purchasing it and was aware of some of the limitations.
The unit is small enough to fit on a counter and occupy a lot of room... Having said that, it cannot hold vast amounts of water at one time.
We have simply purchased stainless steel pitchers and fill them so that when it is a high-use time (Filling water bottles and cups for the day) we are ready to go and don't have to wait for the machine.
The instant hot water dispenser is wonderful for filling tea cups or travel mugs in the morning as well.
Excellent product and have already recommended it to many of my friends.
