Following a failure of the jack on the sound of my laptop, I acherter this key. I am satisfied, music and running again on my pc without having to install drivers. The Windows activates immediately. the sound on my headphones is quality. Clée practice. Unfortunately, I lost a USB port connected to something else (clée USB, external hard drive) but good. Key not too big, just right. I remember to have chosen this key a little more expensive compared to others. good quality and no problem after 2 months of use.
Shipping from Amazon still outstanding, fast and without problems.
