I use this 8 hours a day 5 days a week from a MacBook Air 2013 running at 1920*1200. The OSX drivers are stable, the product only gets slightly warm (other manufacturer's I've had get hot), and it looks better (IMHO) than the other adapters on the market - especially for pairing with a mac.
I replaced a USB 2 display link adapter with this, and I'm pleased with it. For the price - you won't get better.
My only slight niggles would be:
1.) I would have preferred a short HDMI to DVI cable instead of one piece adapter for purely aesthetic reasons. I've ordered one separately.
2.) I would have preferred a white USB3 cabe to match the colour of the adapter - the one supplied is black. Again this is for purely aesthetic reasons, and I have ordered one separately.
Customer service are worth a positive mention too, as I emailed them prior to purchase and received prompt, accurate and honest responses.
