"I purchased two Ephipan AV.IO HD devices recently from them directly. They are a big name in HDMI to USB 3 devices. The software on my Mac computer would not recognize the devices as a webcama as normally would happen. I purchased different devices from a different company for the job I was hired for and then went back to Ephipan to try to resolve the issue after the event. Wasn't an easy fix and since the job was over I opted for a return. I got hit with a 15% restocking fee. That is a chunk for a device that didn't work for me. I should have read the fine print. "
