There is an excellent range of water coolers which made it difficult to choose. We went for the Enki Mains Fed Water Cooler. It was a very easy process, no problems whatsoever. The purchase was immediately confirmed and a delivery day/installation was given for the next working day. Delivery/installation was done by one of their fully trained staff members and it was delivered the next day. It was up and working literally within 10 minutes. The water Cooler looks great in our office, so much so we are considering another one. This is how all purchases should be, no problems, easy transactions, delivery as promised and top quality products. I would definitely recommend Blue Mountain Water, they have set the standard very high and wish all sellers would be as good as them.
