Vacuum Insulated Bottle, 500ml Stainless Steel Coffee Tea Water for Outdoor Sports Travel Keep 24 Hours Cold 12 Hours Hot (Black)

Excellent design, really strong and sturdy but lightweight. No leaks at all, the screwcap is very easy to use and it holds the right amount of liquid for my needs. It's very stylish and is by far the best bottle I've ever had!

The bottle looks great, and worked brilliantly to begin with but 2 months after use it's not keeping my water cold for longer than half an hour. It's still environment friendly so I continue to use it, but it does not act as a cooler anymore.
