The Water-to-Go bottles are really good and we have used them extensively in many countries. While others are buying expensive bottled water and adding to the plastic mountain in the world we just fill up when we need to, assured that the water is fit to drink and we have never had any upset stomach problems unlike some of our travelling companions.
They took us all through Africa from the South up to Namibia and Botswana with no problem.
Water-to-Go saved us a fortune in bottled water and we know if we can find a source of water other than the sea then we will have a drink. I highly recommend the bottles to any traveller.
