I use this adapter to connect a USB3.0 hub to to my 17" macbook pro. It allows me to connect esata card readers for video editing with 3.0 drives. Works flawlessly and very handy. It would be nice if it had a couple extra 3.0 ports on it to eliminate the need for a hub but that's not a deal breaker for me. Worth the purchase!

I bought this because I have a 2011 imac without USB3 support (but with a thunderbolt port), and my older Firewire backup hard drive was failing. There are plenty of cheap USB3 drives available now, and this is quite literally the only adapter on the market (or was at the time I purchased it). It works perfectly, and its nice to have a eSATA port just in case I need one. The only improvement I can think of would be to have an adapter for thunderbolt to multiple USB3 ports, as it is only remotely likely I'll ever use the eSATA port.

I use the bridge to add USB2 and eSata to my 27 iMac. It works without any drama, but the cord needs another foot of length to make it easy positionable.

Works! Plugged my USB 3 hub into the Kanex Thunderbolt to USB/eSATA Adapter on my Mac Mini with USB 2 and it worked. Great device with a very reasonable price.

Works flawlessly connecting USB 3.0 hard drive array to the MAC. Could be improved by increasing the length of the cable it by making the cable detachable do user may use the length that works best for their needs. Dongle hangs over the edge of desk, so it's not ideal, but the product itself works great. It's plug and forget about it. Just works.

Used on iMac for attaching USB3 devices and/or hub. Also for using an ESATA external hard drive. The Thunderbolt cable is a bit short for an iMac, although it's obviously fine with MacBook. It dangles from the Thunderbolt port on an iMac, rather than laying flat on the desk. Otherwise it performs admirably.

I use this adapter to connect a 6tb RAID 5 eSATA enclosure as well as various USB 3 drives. This adapter has performed perfectly for the last four months. I have not had any issues with the design or quality of this adapter and would recommend it to anyone who needs such an adapter.
