Very good resistance over time ...

Simplicity sometimes good: after trying several systems with silicone straws we faced the following problems:
- Straws find themselves completely chewed
- It is impossible to properly clean these complicated assemblies

Here no problems, the tip hard plastic supports attempts machonnage (some bear traces remain functional but ...) and ultra simple assembly (pot with lid, nothing more) is used to clean all .

In addition lapprentissage is facilitated by the ability to use it as a glass: plain glass table and glass tip at night or on the go.
