Really quality device - well worth paying a bit more and getting a nice, solid device than paying a bit less and getting junk. For XBOX One you only need a 1x2, but I got a 1x4 because I plan on adding a second TV soon and with this installed it will just be a matter of plugging in another HDMI cable and set to go.1) Yes, it works wonderfully with XBOX One and it's HDMI input.2) This is a SPLITTER. It takes ONE signal and allows you to split it's OUTPUT, identically, to multiple devices. It is not a SWITCHER (to allow multiple devices to switch between one input) or an HDMI Matrix (which allows you to mix/match multiple devices with multiple monitors).The build quality feels very professional - no cheap plastic, nice metal housing. After days of use it's still cool to the touch, no overheating (or any heat at all). I really didn't want a device that had to be plugged into electricity but on researching many devices, I've found that most of the ones that just rely on the HDMI provided power simply aren't reliable enough. The only complaint I had is that it's one of those "sideways" plugs, so it can be difficult to place. It was a small price to pay, though, for such great performance.I have a Sony receiver that most of my equipment (except for the XBOX One) is connected to, and the output HDMI is hooked into the splitter. Then the splitter splits into two HDMI - one that goes into my TV, and one that goes into the XBOX One. This way, I can watch anything normally as I always did, but I can also route it through the XBOX One to use the SNAP/TV feature. It's a perfect set-up for my needs. As I said above, I am adding a second TV soon - I considered a HDMI Matrix, which is far more expensive, but since all I want to do is play XBOX One while watching other content, I really am not going to need one. Adding another TV to this device will be fine - it just gives the option of not having to use SNAP on XBOX One and watching two different things on two different TVs. That said - again - if you want to hook all your sources into this directly and matrix them out to multiple monitors, this will NOT work for you.Very pleased, glad I didn't go through several inferior devices before getting this one. Was five minutes to set up, worked instantly and of course since it's not analog there is no reduction in quality. Now I have a lot more options and already have future expandability - if you even think you will ever want to add more devices (with the 80-foot possible HDMI output, you could actually route it to another room), I'd pay the extra $10 to get the 1x4 like I did - but in any case, high quality product, just know what it is you need and what it is you are buying.

I use this splitter to get my HD cable TV feed from a DVR in our family room to the kitchen. It required a 30' HDMI cable (I am using an Aurum Ultra HDMI cable)and some fiddling around to run the cable, but that was the hardest part of the job. I was somewhat concerned about hooking up a second TV from the cable box, because it seems as though HDMI is finicky. One problem I ran into was that I attempted to split the output signal from my surround sound receiver to my Panny 60" plasma set. The advantage of this approach was that my Blu Ray player could also go through that single HDMI cable via the receiver, so in theory, I would be able to watch any cable or Blu Ray content on both TVs by passing the signal through the receiver.However, the receiver (Pioneer Elite VSX21) wouldn't pass the audio through, and certain features on the DVR box no longer functioned on either set (specifically 3D output, and the on demand channel). So, I had to split the HDMI signal out of the DVR box. Once I did that, everything functioned perfectly. Just means I had to pass on watching Blu Ray DVDs in the kitchen. To continue to be able to use my surround sound system with the Panasonic, I had to run a digital optical audio cable between the TV and the receiver, since the cable box is no longer hooked up to the receiver via HDMI (the DVR box only has one HDMI output).I cannot say how well 1080p would work, since the best the cable box can do is 1080i. However, the picture is perfectly clear on both sets, and there is no noticeable signal lag. It just takes a few seconds for the splitter to figure out what it is doing.I got a second remote for the DVR box that I can leave in the kitchen, and got a Next Generation Remote Control Extender so I can control the DVR box from the kitchen, even though it is located in the cabinet in the family room. It works great! Now I can watch anything in both rooms, and have both TVs on if I want to run to the kitchen and grab a beer or snack and not have to pause the programming. Plus, I have the satisfaction of knowing that I don't have to pay the cable company for another box for the kitchen that can output HDTV, so that'll save a few bucks every month. I'll recoup the investment for the cable, splitter, and remote extender in less than a year. I am thinking about running an HDMI extender via Ethernet to an upstairs TV, since there are still 2 splitter ports left on the J-Tech box.In retrospect, I might have opted for a 2x4 matrix splitter, then the Blu Ray thing would probably have worked, but my main mission was to get the cable feed to the two TV's, and for that, it works great. Not sure what will happen if both TVs are on and I try to watch 3D content on the Panny, my guess is that the HDMI signal will get "dumbed down" to the lowest functionality available on either set. Since the second set doesn't support 3D, I assume I'll have to turn it off in order to watch 3D on the other set. I'll post an update once I try it.All told, all long as you have realistic expectations and understand how to hook things up, this unit works great. I haven't seen any overheating or other issues yet, but I've only had it running for a couple of weeks now.
