Quick and fast HDMI switching at full 4k@60hz. That's what I needed it for and that's what it does. Product feels really well constructed and remote does what it needs to. Device provided faster HDMI switching than my TV. Great for all those 4k TV's with only one or 2 HDMI inputs that truly run at 4k60hz as opposed to ones that say 4k and are just at 30hz. Get this is you have multiple devices that need 4k@60hz. Also does the audio transfer with it. 5/5 in my books. You pay what you get for. No complaints.
