I purchased this adapter because I use my MacBook at work & at home. At home, I use it to connect to my HDTV and at work, I use it to connect to my monitor (via DVI connection). I originally purchased a separate adapter for each purpose (from another supplier), but the HD adapter stopped working after a few weeks of use. This is a perfect replacement, works great for both purposes (in one adapter now), and quality seems much better than the one that stopped working for me after very little use. MCM shipment was on time as well!
Excellent! Great prices, well packed, shipped fast.
