Thunderbolt to USB3/SATA Adapter?

Did a search in the forum and couldn't find anything...

Anyone have any experience with the Kanex Thunderbolt to USB3.0/SATA Adapter.

Looking to expand capabilities on a mid-2011 iMac.

Specifically wondering if there are any sleep issue with external devices (both USB3 and SATA) on Yosemite.

Thanks

Thanks I updated my question -- forgot to include the Sleep portion in the original post. There is only 1 mention of "Sleep" in the reviews and it's problematic (1 star):

"...Among other things, both had trouble recognizing hard drives attached through USB3, and neither would dismount the drives properly when the computer went to sleep. I kept getting a message that I hadn't dismounted the drives properly. The adapter is supposed to work with OS 10.8.4 or above. I was running 10.8.5 and made sure that the latest Thunderbolt firmware was installed on my mid-2011 27" iMac. I tried different external hard drives and cables and everything else I could think of with no success. The adaptor is flaky at best. It's a shame. I would love to have one that works. One star is too good a rating"
