Very good, I haven't noticed any interruptions in the image so far and I've had it for a long time. The devices I have connected to it are the PS4 Pro, Nintendo Switch, and Xbox Series X. With an HDMI 2.0 cable from a good company to connect it to a monitor/TV, it also supports 4K resolution with HDR at 60Hz normally. The remote control works very well.

I recently bought it. For now, it seems to be working well. However, there is an issue with the remote control. It cannot change unless it is next to the device. Essentially, it is useless. I complained, considering it faulty, and requested a replacement, but I also read in another comment about a similar problem.

Connected to my Toshiba UHD TV, which only has 3 HDMI inputs. I connected my PS4, DVD player, and an additional decoder (OSIO) for any recordings, and it works perfectly! As for durability and reliability... if any issues arise, I will update.

I bought it with reservations due to its low price, but I was surprised by the fact that it does exactly what it promises. I connected my PC (1080p), Ps4 Pro (4K), and Ps3 (1080p) to a Samsung 4K TV with HDR. It works flawlessly with all three devices, without any issues with resolution, sound, or disconnections, etc. Fast switching between devices. You won't need anything more expensive. There is also a version with 5 inputs. I would definitely choose it again.

Stable and reliable. Used for connecting monitors to PC and PS4. The only issue is that the controller needs to be aimed precisely to change the source.
Edit: After one year, it broke...
