I just bought it to connect a second external monitor to my 2-year-old laptop with an i5 processor and an HDMI output. It works perfectly, I just had to do a little research to figure out how to support a resolution of 1920x1080, but it supports it flawlessly (although it might be my fault for not immediately finding it because I threw away the packaging without reading the papers - because it was hard plastic, I was afraid of cutting myself when taking out the papers).

Since we also use the same thing at my work on a newer laptop with a more powerful processor, I know that occasionally it disconnects but it's not something drastic and it reconnects immediately (maybe once or twice every 8-9 hours). Of course, I use it for coding, I don't know about its performance in games, etc.

From the beginning that I received it, it started disconnecting, which has become more frequent after 1 year of use... bad product

It works. While most in this price range don't do the job. It has input lag, which is expected. Not for gaming, but for browsing on that screen it's fine. Also, something that competitors don't do is that it works with an HDMI to VGA converter. For now, satisfied (1 week)
