Pros: This switch hooks up easily, and works well. I have an older 7.1 amp with no HDMI plugs, but it does have optical receptacle. My 1080I TV has DVI in, so now I have a way to use some some new audio/video devices. This will give me another couple of years on my old gear.
Cons: I have not been able to pass a THX Ultra2 signal through the optical receptacle on this device. For instances, the ATT set top box has HDMI and the video which passes through the 4 X 1 switch will give me 1080I on the TV, but it will not pass THX Ultra2 sound through the optical out to the amp. However, when I hook directly from the ATT set top box to the amp, I get a THX Ultra2 signal.
Other Comments: Overall I am very satisfied with the HDMI Ver. 1.4 4X1 switch.
Pros: Excellent picture quality. Small size. Includes a hilarious user's guide due to its really bad translation to "English".
Cons: HDMI connections are on the left, rear, and right so you have to leave ample space on both sides. The manual has tiny print and is completely uninformative. The troubleshooting guide makes no sense at all. The remote is cheap. The red power LED -which seems unnecessary- on the front is about 20 times brighter than the green signal in/out indicator LEDs.
Other Comments: What is ARC and SPDIF? Never mind, I'll see if I can find it somewhere on the Internet.
Pros: Excellent service, excellent well priced products. Excellent tech. support. I can't think of anything they could have done better. They even have real people answering (promptly) the phone!!
Pros: Simple and straight forward. Easy to use. Had everything hooked up and ready to go in 5 minutes.
Cons: I wish all of the input and output ports were on the back of the box instead of some of them being on the sides.
Other Comments: I haven't tried out the Ethernet port or SPDIF jack yet. Be sure to power down any of your video sources. I initially had no audio with my Dish Network Hopper box, but after rebooting it I finally had my audio. I tested out the HDMI switch with my Roku, Motorola Xoom tablet and laptop as well. Everything works well on my 6-7 year old 61" Panasonic 1080i LCD projection TV.
Pros: This switch was very well made and was easy to set up.
Cons: It didn't work with my 7 year old TV. I had to purchase the 3x1 switch instead.
