Review on Collapsible Reusable Foldable Eco-Friendly 8 Oz Water Bottle (3 pack) - BPA Free, Travel-friendly, Compact Design by Edward Mcnamara

Service life approx. 9 months. I use one at a time until a leak occurs, always in the seam/seal. I will buy them again because they are so portable, fit in a small purse, in the cargo pocket of my shorts/capri pants and are the only 8 ounces I can find on the market. When they work, they're great. The three of you go. These three lasted two years and were used individually until they were phased out.
