I used this to add USB 3 capability to a Mac Mini. In this capacity, it works perfectly.It's a cheap way to get faster dives on you system. However, the eSATA half of the adapter has issues you need to know about. It works perfectly if you only have 1 drive plugged in, but if you are using any kind of enclosure that has more tha 1 drive in it, like one of those dual drive bays, you will have problems with it. This is because the adapter does not support eSATA port replicators and a multi drive bay basically acts as a port replicator. Other than this issue, it's a 5 star product.

Tried to use it attached to a backup drive to restore my system on a newly installed drive. I was disappointed that my Macbook Air doesn't recognize the drive through the Lightening port to the USB 3 port until I had first installed OS X. I had to put the drive on the USB 2 port on the Air to do the restore. Once the OS X was installed it worked mostly fine. If I leave it plugged in for long period of time the drive used as as Time Machine Backup will disappear from the computer though it is still attached. I have to unplug it ( the OS complains that the drive was not properly removed) and then plug it back in. The drive reappears and can be used again.

I use it to add 3.0 capabilities to my mid 2011 imac, i like it a lot, i used attached to a 3.0 usb hub, i dont like that it so bulky, also the cable feels a little weak (maybe its just the feel, we'll see) and maybe i would put a thunderbolt port instead of the sata one

Product works great, but the length of the cable is not ideal, makes it hard to position it depending on the situation and desk environment. I would have either liked to see a longer cable (3'-6'), or allow us to use our own thunderbolt cable (possibly lowering the price). I have issues sometimes where the eSATA port is disconnected when the adapter is moved; this is a problem on my setup as it is connected to a 4 bay RAID drive. I don't move it often, but i do unplug my MacMini from time to time to blow out the dust from it. Otherwise it was a worthwhile investment to update my MacMini 2011. I really needed USB3.0 bad, and eSATA was sweet as I did not want to invest in a new RAID enclosure quite yet.

I purchased this to use with my IMac 2013 27". It works great. It does what it is supposed to do by giving you the advantage of the IMac's thunderbolt connection.

1. Use USB3.0 or eSATA storage device with 2011 iMac 2. low price and simple composition, specially do not need external power 3. Thunderbolt cable is too short, but I think it caused for low price. (Can't use thunderbolt bridge, too) 4. It's been wat too long after Thunderbolt geration.

I've had a good experience using this adapter to connect USB 3.0 and eSATA external hard drives to my MacBookPro8,3 running OS X 10.9.x. It has worked very well. It sometimes takes a little while for eSATA drives to mount, but I think that's a limitation of the eSATA implementation on OS X. Overall, I'm very happy with this adapter.

Had this little device for several months. Just exactly what I needed for my 2011 MBP sans USB 3 but still featuring a thunderbolt port. I do large file transfers and can get 100GB to transfe USB3 to Esata on the device in roughly 15-20 minutes, depending on drive speed. Works great! One note, if you are going to use bus powered portable usb 3 drives, I have only had success on 2TB and smaller drives. The 3TB drives seem to need more power and the adapter has worked intermittently.
