I have bought 3, I use them daily for 6 months now and I am very satisfied. No problems so far

It has been working flawlessly for about a month that I have it. I have used it to connect 2 laptops to one monitor, I haven't tried the opposite. What made a positive impression on me is that when you switch from laptop 1 to 2, laptop 1 returns to a state without a connected monitor.

Amazing convenience for the work it does at its price. And its quality is definitely not low

I've had it for about a year, it's plug and play, there is no difference in the screen quality. However, if I would change something, it would be that the screen shouldn't require both devices to be on in order to turn on

Recently purchased for connecting a TV box to the computer screen. Seems like a quality product. Quick switching between the 2 inputs (computer - TV box).

Many times you need to press the source twice (e.g. you are on 1 and want to go to 2, you press 2, it doesn't catch it, you press 1 and then again 2 and it will catch it). Apart from that, hassle-free operation, time will tell, I have had it connected to a laptop and desktop on 2 screens for about 3 months.

It works perfectly from two inputs to one output. Plug and play. Obviously, one input is selected at a time.

With closed eyes. I bought two and have connected a Desktop and a work Laptop to two screens. With one click you change the source. 3 years owner and they have shown no problems. If you are considering a similar setup, you will also need 6 HDMI cables

The device works perfectly as a switch on PS5 with a 1080p signal and does not require an external power supply. It sends the PS5 image either to monitor 1 or to 2. In fact, I have connected a 10-meter cable to one output and it works normally without any breaks or interference. A positive aspect is that all connections are at the back, so the cables do not get in the way. On the downside, it starts with the 1st output activated and not the one you left it on.

It does what it says at a fairly low price and in a very simple way. Small in size, discreet, and in a nice color. By pressing a button, you switch from one screen to another.

Value for money! It does exactly what it is intended for. I have had it for 2 months and I am completely satisfied. (Connecting computer tower with monitor and television)

Very good product that can be connected either with HDMI cables or with HDMI/VGA converters in case the TV has only one HDMI port and one VGA port.
I have three of them, and one is connected to an old TV as I mentioned before, and I have it in the video, the second one goes from one port of the splitter to one input, and from the other it comes out of a device and connects to the TV, and the third one outputs the box to two TVs.
Note: It switches quickly only with plain cables, if you use a converter like I do, it takes a bit longer to display the image.

I bought it to quickly change the image on the screen from the computer to the Xbox s.
Excellent, very good build quality for its price, it does exactly what it should and it is also beautiful. I will leave a picture and video.
*WARNING: It does not come with an HDMI cable, so you will need to get one if you don't have it.
Update:
After a few months, there was a power outage in the house and it stopped working. It seems to be of poor quality

Very good value for money! The only thing that concerns me and prevents me from giving it 5 stars because I haven't figured out yet what the problem is, is the following: I have it connected to a monitor from 2 laptops. When both laptops are connected and one of them is closed, it sends some power or signal to the HDMI of the closed one, causing either the fans to turn on in one laptop or the USB ports of the other laptop to receive power, as I see the LEDs on a USB hub connected to the second laptop flickering. I don't think it's an issue with both laptops, but I can't imagine what the HDMI could be doing.

It is slow to respond, forgets which input was selected. I disconnected/threw it away several times until I found the way it responds. If connected correctly and with patience to find the way it works, it does its job.

A little gadget that does its job as it should.
EDIT: After 2 months of use, it hardly recognizes devices and doesn't transmit anything through cables. Another powertech device that I have, works perfectly on the same network.

I wanted to easily connect my work laptop to my desktop monitor. So theoretically, 2 inputs to one output. When it arrived and I saw that it has 1 input and 2 outputs, I thought I bought the wrong device, but in the end, everything is fine, it can probably do both (?). Fast switching without issues. When I connect the laptop, the second monitor from my PC turns off, but I think this is because they are connected with HDMI and not with display port, and it's not the Switch's fault.

It is small like a small lighter and very high quality in terms of construction! It does its job perfectly, it is 4K and has a metal casing. The front panel has a bright indicator for which of the 2 HDMI ports is currently working, and the back has the 3 HDMI ports. It is cheap and BASEUS brand, a company that has entered the market strongly with many high-quality products. Overall, it is worth its money!

Terrible product, I wasted my money! Do not buy it, it doesn't work with 2 computers (1 desktop and 1 laptop on one screen) and it only functions when both machines are powered on! If only the laptop is on, the lights turn on very faintly as if they don't have enough power. And yes, I tried it with different cables, some HDMI 1.4 and HDMI 2.0. Completely unacceptable.

It arrived quickly, without any damage (neither to the device nor to the packaging), and it was very easy to install.

It works perfectly in switching between TV and computer monitor, with very good image and sound quality (I don't have a high-definition TV).

The only drawback is that it takes 3 seconds to switch the image and sound between the TV and the monitor (which I consider negligible).

Flawless little machine! Small like a matchbox and without extra power supply. Be careful, it does not output image to 2 screens simultaneously. You choose either one or the other. For 9.7 euros, it is more than value for money.

Reliable, well-built, does exactly what it says in the description. Since it does not have its own power supply, if you want to connect a large TV at a distance you will encounter difficulties. The signal will not reach.

It does what it promises, I have it connected to a laptop to switch the output to 2 screens. Be careful, it cannot output simultaneously to two screens, you simply press the button to switch between one or the other. It didn't present any problems, plug and play.

Excellent product. Very small in size. It does what it promises.. For any disconnections, etc., try a higher quality HDMI and the problem will be solved.

Excellent build quality (metal chassis that does not heat up). It operates without power supply (POSITIVE), it is a switcher and matrix switcher, meaning that the 2 HDMI inputs are also outputs that allow the connection of 2 screens or TVs. It does not support simultaneous signal display as it is a switcher and not a splitter. It makes a difference if you use high-quality 2.1 HDMI cables, it is the 3rd one I have purchased!

Very good, it works without electricity and has very good image quality

Everything is fine so far. It does what it's supposed to correctly and without any problems.

I have connected two computers to one monitor and the switching works seamlessly by pressing the button on the top of the device, while it also has the corresponding indicator lights.

And the 3 cables I used for this connection are HDMI v2.0, in order to have the best possible image.

Very small in size, so it doesn't take up any space on my desk.
HDMI cables are not included, of course, you will need to purchase them.

Very good product for the price you pay. I bought it about a month ago to convert the 2 HDMI ports on my old 32-inch LCD TV to 3. It doesn't require power supply. It would be perfect if it didn't get stuck in standby mode (meaning it automatically switches to the other port or you just need to press the button twice to switch back). This could also be due to compatibility issues with the devices. Regardless, for its specific purpose, it's great. I would buy it again if needed.

Excellent product. It has a button on top to switch between 1 and 2 HDMI. The only "bad" thing is that you need an HDMI cable to connect it to the device (I thought it would be included). Otherwise, very good picture, a worthy product
