I received the stick for 50.45 euros on 09.04.2014 and tested it several times on my MacBook Pro and the Thinkpad W520i7 with USB 3. Repeatedly I had when reading stable transfer rates von170 MBit / s and write at up to 110Mbit / s where da mostly leveled off while writing to 100 Mbit. I have 126 GB of training videos, drivers and apps in 11min. had on the stick. So far I can not say anything against the stick. The housing not creaks. When MBP is usual aluminum housing so it looks a little cheap but on the processing can not complain anyway. What makes me the decision to stick always a little hard, the frequent lack of transfer rates. That is why all the prayer when you buy a stick, please write a review with the transfer rates and what you have saved. Many thanks. Allen who opt for this stick a lot of fun with it.
