I bought this stick in January. The speed test was outstanding, but I immediately wondered how to give lifetime guarantee against something that contains moving parts. Exactly I mean, the slide in order to push the USB plug in and out can. Now after nearly 5 months it is defective. First you had to slide when inserting the stick forward so press the stick was inserted. Shortly afterwards, he has slipped slightly despite advance so that the connector never really in port and the USB stick was thus was unreadable.
Amazon has paid me the full money back with no problems and I'm going to buy in the future USB sticks without Slide.
Which incidentally concerns the Lifetime warranty you have to be able to take advantage of this to send the USB stick at his own expense to the Czech Republic. But in order to take him at all to complete you need the serial number on the back of the stick, which after 4 months was relatively unreadable for me. So (simple imprints) The "lifetime" warranty has a very nice hook.
