Prior to working with Artesian, we had not been given the option of a bottleless system from our bottled water supplier (although apparently, they also had one). When working with the team at Artesian, it became clear that in addition to a cost effective solution (at volume) a closed system meant cleaner water available to our staff and customers.We had a concern about the contract, but the team at Artesian worked to fix the problem in a fast and efficient manner. They have earned our repeat business.As for the system, it works great. If there are any complaints the cold is too cold, which is really no complaint at all. We are very happy with our artesian system.
