First, the key is very small and thin, too bad we can not see the pictures on the site. For my part, I appreciate this small size, to give you an idea, it is the same as the tip usb epaissant Iphone5 and it is 2 times its length). in terms of transfer speed, it's okay for photos and videos. otg tip is recognized on a straight galaxy S4 and also my asusT100 tablet win8. usb nickel tip on my mac. by against small problem as the body of the key is in brushed aluminum (nice effect) I had a little trouble to insert the USB port on my TV. otherwise I am very happy with this purchase and provided the same kind qu'Emtec with MicroSD reader: D. nb: the OTG tip is protected by a plastic cap independent, and there's a small hole to insert a cord or key holder ring
