Update: Contacted seller regarding faulty adapter. The seller kindly responded and sent a replacement. Replacement adapter received same week. Use it and it works! Very responsive customer service! Original: One of the adapters failed after less than 20 uses. The video stutters all the time while our video devices are connected to our computer through a faulty adapter. Switched to a different adapter and the video works fine. Externally, the adapter makes a very robust impression, but a defect is a defect. It may just be some flaws, but we'll learn more in the long run.
