Bottle perfect, absolutely tight and easy to handle

My 14Monate old son has been drinking with almost half a year from this bottle and can use it alone. She's tight in every position and filling, even carbonated. In addition, they are spaces in the dishwasher and also disassemble the vacuum cleaner without problems completely.

The only drawback: each offend, each drop has with absolute certainty a dent, Macke, or at least a scratch to follow.
