This device works well for me. I'm using it for HDMI, USB and Ethernet. If it had a pass-through power port so it could charge the laptop, it would be perfect.
I would recommend this product to a friend!

I had not needed any T3 or 4 goodies in some time and had moved without changing my address ; I realized my error after clicking the order placement. I immediately called cust. serv. for correction. This could not be accomplished without re-ordering. They cancelled te order, I adjusted my info, and re-ordered. Bada bing bada boom, 3 days later I had my unit. It's difficult to be annoyed with a company that treats a nudge like myself well. OWC is still and will be one of 2 go-to Mac-related outlets. Regards, Ed Fiala
