Sean first introduced himself to me after seeing another company delivering water bottles to our office. He explained the reverse osmosis system and whilst I was a little skeptical at first, thanks to Sean’s extensive product knowledge, I was soon convinced that this was a more efficient and inexpensive way to drink clean refreshing water than the bottles of water we were currently being supplied with, When I telephoned my current water supplier to cancel their bottle service, they offered what appeared to be a similar reverse osmosis system for a cheaper monthly price. When I advised Sean of this he was extremely surprised and I told him I would need to conduct further research into what was available before committing, to ensure we were receiving the best value for money service. Later that day, Sean contacted me to advise that he had personally telephoned our water supplier to enquire about their system and had learned that it was in fact different to the system Crystal Water was offering me. Once Sean explained the differences to me and upon my own confirmation with our current water supplier, I discovered that I was not comparing apples with apples. I was very impressed with Sean’s efforts to ensure I was well informed before making a decision, all without being pushy or overbearing. Sean’s professional manner and product knowledge was the reason I looked no further. The installation of the system was quick and painless as promised, with no disruptions. Sean was extremely professional and friendly and I would not hesitate to recommend his services. It was a pleasure doing business with him.
