Water bottle Burga
At first I want to say that i'm really impressed about this product from Burga. I want to give you an example: This morning at 8 am before I went to my exam, I filled the water bottle with water and some ice cubes (maybe 5 cubes). Most of the time when you fill a water bottle with water and ice cubes, 1 hour later you water bottle is a bit colder, because of the ice cubes, but after 2 hours your water is not so cold anymore. But this water bottle is so good. When I came back from my exam. 4 hours after I filled the water bottle, and you have to know that the bottle has been in a room of 22°C for like 4 hours out of the fridge. When I drank my water it was so cold. It seemed that my bottle had stand in de fridge. It was amazing to have cold water after 4 hours out of the fridge. So it meens that the bottle has a very good quality
