Have brought only one reason me this converter; I still have a 2.5 "disk, which has a USB2.0 and eSATA interface; well and USB2.0 is not the best if you have used the eSATA port. The adapter was there pretty fast. Have tried to be unpacked and immediately. He also has no mucking his service (and also with the appropriate pace) done. The display indicates whether the Gärät works, you siet by two LEDs under the dark plastic cover; One is to display the connection and the other for the throughput. Use the InLine today and am very zufriden. Thus me a Kausfempfehlung.
