Hi @Amel NASRI​ Thank you very much for your answer.But in fact, I do not understand what is so special about this model that it is so requested worldwide.  Do you have any estimates as to when that might be available? Thank you again--Zoya

We are a very large, very bureaucratic company. We are working with registered suppliers only. They do not have this device in stock for at least a half year and they have no idea when it will be back in stock. My team can't work without it
