Review title: Problems with 2 units.
Product review: The reviews for this product are excellent and I was so excited to upgrade to HDMI switching. The first unit received had a loud hum in the audio and HDMI from my new Sony player through this unit created an extreme blue cast on the video. I returned the unit and another was sent to me. This unit had no hum in the audio but the blue cast was still there when using HDMI from the Sony DVD player. It was not the DVD player because when I hooked the HDMI from the DVD player directly to my TV everything was perfect. I am very disappointed in this unit. As for Amazon, they have been great in responding to my problems, getting a replacement unit to me and then refunding my purchase. I give Amazon 5 stars.
