After only two months leaking

The function of this bottle does not run after the normal straw principle. The plastic tube is scratched up. You have to crack a crack his teeth vigorously, so you can suck up water. That's the question of whether one appeals to the besonsers. Now the bottle was also leaking very fast. It now trickling from the crevice when the bottle is standing upright, such as in a pocket.
Conclusion: would not buy again the bottle.
