Device failed in less than 3 weeks. At first I thought the problem was the Comcast cable box, which I've changed three times. Finally, a Comcast technician came to my house. He tested all of these and found that the problem was in this Prozor extractor. He also discovered that his HDMI cable was broken. This is a case in point why we can expect to waste our precious time returning a large percentage of the items we buy from Revain. I wish Revain could limit sales to products that meet acceptable quality standards.
