A bottle is difficult to assess because it actually has only a function that you need and that can pretty much each bottle. Keep liquids and you have to be able to drink it. This can this bottle. I have given 5 stars because it is very stable and they can be used well a long time. I have it already often fall behind and it has gotten only a few scratches. One can very well drink from and it is also quite easy, that you can take with you anywhere. The liter display I have not yet been used, but which is intended also handy when you want to mix something in it. Brushing it can also be pretty good. Overall, a very successful product. Can I recommend.
