We ordered this bottle because we finally wanted to get away from these Silikontrinktüllen. Unfortunately, our dwarf needs it very much sucking (already is saugfaul) to get something out. If you open to fill liquid after, you get it no longer properly sealed. It must first complete the upper part to be taken apart and dried. In addition, the bill is quickly scratched by the teeth, which we did not have in others.
