Listening and autonomy are good but I am not satisfied by:
- Hyper-sensybles keys; it is enough to brush against one and presto! Your tel. is turned on without your knowledge.
- It sounds max. 5 times is enough. I miss two-thirds of my calls.
- Especially since there is no memory indicating what number called you.
Now, I do not exclude that I have not been able to find all the functions to use it properly.
In any case it is too complicated in my opinion.
