This extension is absolutely bad processed. USB Flash Drive does not fit properly in the lead since the socket is too tight. The plastic protective stops so that you, the bare contacts only sees. The USB stick was now up stuck only once from me, because it is the stick for a keyboard, remove and use different drives is no longer possible. Therefore, the Council: Stay away from this absolutely lousy Accessories! The one star here refers only to the fast delivery, the extension would have to be "rewarded" with a minus star. If only the seller would be assessed give it 5 stars, it's all about the product. A tip to the seller: best to take this product out of the range!
