I was at first skeptical about the Water-to-Go bottle as I already was in possession of a competitor’s product and felt that was adequate.However, since switching to the Water-to-Go bottle there has been no looking back. Not only is the filtration system more advanced offering for better hygiene and taste when using the bottle I found the design, shape, and build of the product very strong. Perfect for office use as our tap water in the building runs cloudy. The durable bottle also means it is perfect for when I go to the gym during my lunch break. My office is now looking into personalizing the bottle and ordering some for the entire office.
