Worked but just not always
Build quality is fine it’s worked fine with my blu ray player and cable box out putting to my tv or projector when needed. But I ran into issues with Xbox series x and ps5 often need a power cycle, I gave a number of different hdmi cables a try including optical ones no difference. And while playing gran tourismo picture would for a second of 2 get pixely I’m nit sure how really to describe it. There really is a market for some thing like this I just wished it worked always. It’s worth the price tag as do me it would save me form switching hdmi cables between, my atmos processor, projector and tv maybe a firmware upgrade will fix these issues

Awful and simply doesn’t work
Product is absolutely awful. Do not buy this product. The channel switching doesn’t even work. You have to turn the device on and off every time you want to switch channels. It also won’t connect to my laptop says the resolution won’t match and no matter what you do. it doesn’t work but most importantly, this is advertised with a remote and channel switching that simply does not work every time I switch from the PlayStation to the Xbox. The screen just goes black and I have to restart the device every time do not buy this.

A good unit to buy - Does what it claims and excellent support from OREI!
I bought this unit to make up for the shortcomings in both my TV (a 2022 model Samsung "The Frame" 55") and my Logitech Astro A50 X (has a 2-port HDMI 2.1 switch that is provably faulty, unfortunately). When I first received the BK-402A, it worked flawlessly with my Xbox Series X but not with my PlayStation 5. Unfortunately, the shipped firmward on my unit was not compatible/working with the PS5 and its strict HDCP 2.3 configuration. The unit refused to send a picture to my TV. Now comes what I think is the best part: OREI technical support. It is strictly via email but their team is responsive. There is a bit of a time lag but patience will bear positive results if you contact them. I explained my issue in detail, going so far as to buy a cheap-but-well-reviewed competitor switch (not matrix) device as well as replacing my HDMI 2.1 (UNCERTIFIED) cables with cables that have the HDMI.org certification tag on their packaging. With a full explanation provided, the OREI support team worked with their "technical team" and ultimately sent me a firmware upgrade that proved to be the solution! NOTE: The upgrade process does require a PC but is documented for easy processing As for the product itself: Metal casing = premium look-and-feel. Port options are plentiful. The 2-port output option might come in handy one day, which is why I opted for the matrix instead of a standard switch. (See OREI's excellent Youtube video that explains what an HDMI Splitter vs HDMI Switch vs HDMI Matrix are, if you aren't aware.) Thank you, OREI team for producing an excellent product and then also proving that you really do stand behind your products with excellent technical support. You have earned a return customer and I will be recommending your products to friends-and-family. :)

Working fine
Working fine so far..no complaints as of now. Build quality is great and better than other. Outer shell is metal most likely. Remote signal is stronger than others. Tested with Mac Mini and Windows and its compatible. No issues with sound passthrough. Value for money purchase at 5k INR

HDMI Switch used for Gaming Consoles, PC and Home Theater
I’ve been using the Orei BK402A HDMI Matrix Switch for about eight months now. After working through some initial setup challenges, I can confidently say this device performs well—especially if you’re running a mixed HDMI 2.0 / 2.1 setup like I am. My goal was to route my game consoles or PC either to my TV for audio/video or through my AVR while maintaining full 4K at 120Hz with HDR, VRR, and support for various surround sound formats. I reached out to Orei’s support team several months ago and stayed in contact with them while troubleshooting. They were responsive, helpful, and genuinely committed to resolving the issue. That level of customer service is rare and significantly improved my overall impression of the company. In the end, the HDMI handshake issues were resolved through a combination of HDMI firmware updates, using specific HDMI ports, and dialing in the correct power-on sequence.
