This Gana 3-Port HDMI Switch works well for us. It seamlessly turns one HDMI port into three and the remote control feature allows for easy tuning, especially if using a universal remote like a Harmony 650 (more on that later). This item has a very small footprint, which allowed me to mount it to the back of my TV. I used 12 of VHB 3M Adhesive Double-sided Foam Tape High Bond Conformable Acrylic Glue Replacement Kit 1.5 x 3 Inch Rectangular Plus Alcohol Pad to accomplish the mounting, but this diminutive switch can surely be affixed by any number of methods.There are several brands out there that look nearly identical and work exactly the same. In fact, I purchased this switch to replace another one that looks and functions the same, but that failed after 4-1/2 years. I first tried another brand (that also looks the same), SMARTOOO 3 in 1 out HDMI 1.4v switch 3 ports HDMI switch 4K / 3D auto switch / remote control, but it did not smoothly switch from input to input and had to be returned. On the other hand, this Gana Switch is very responsive and works better than my original switch ever did and certainly better than the one I had to return. I also like that the indicator light on this unit is red, rather than obnoxiously bright blue.This brand/model comes with a power cord, but it is not needed for my application as power is supplied by the devices installed as inputs (in my case a Roku 3). This switch works as described - I find I need the remote control feature because the auto-switch function is not as useful when you have inputs that don't power off (e.g. a Roku). I don't detect any difference in picture quality going through this device (I do not have a 4K TV or signal, so I cannot comment as to that).While I need the remote control feature, I don't use the remote that came with the switch. Instead, I rely on a universal remote (otherwise I would need 5 remotes for the setup pictured). My remote of choice is this entry-level Harmony: Logitech Harmony 650 Infrared All in One Remote Control, Universal Remote Logitech, Programmable Remote (Silver). There are more expensive Harmony remotes out there, but for line-of-sight applications this is all you need! This switch is compatible with the Harmony 650 remote, but it is not recognized by the MyHarmony App that programs the remote (this is the first device I've found that is not in Harmony's database). This means that the switch needs to be added manually, but there's a slight hiccup. When you follow the MyHarmony on-screen prompts it displays an error message about the model number being for a remote (not a switch), so you can never progress to the options that allow adding a device manually. The Harmony help forum & Google were of no help and I almost returned the switch. However, I realized since the switch was not recognized as a device in the Harmony database all I needed to do was enter a bogus model number (one that would not be mistaken for a remote control). Once I entered the bogus number, the on-screen instructions walked me through adding the switch manually. It has been working perfectly since then.Summary:Pros: Small, responsive, remote controlled, sensitive remote, red (vs blue) indicating light, 3 HDMI Ports from one.Cons: Not in the Harmony device database, so harder to add to universal remote (but this is really a Con for Harmony, not Gana).I recommend this product. The four-star rating will be upgraded depending on durability ( I want better than a 4-1/2 year service life for a higher rating).
