Let it be said that key is pretty basic, even happening everywhere. This is a rather impersonal product whose primary objective is to store data. And this role she is doing wonderfully well since I use it for some months now and there is nothing to report. She spends most of her time in my right jean pocket alongside my Navigo card and I did not notice any interference between the two technological tools that coexist beautifully. I bought it in a hurry after losing another key and I must say I would do this purchase if I were the same. This is a good product of the EMTEC brand, which literally means "love technology", unless I invent.
This key is a credit to the family of USB flash drives.
