At first I had an image, then I had none at all, I caught it after a while and it no longer works at all, the laptop screen flickers and shows nothing.

I connected my laptop to a 240hz monitor to have gsync, unlike the HDMI port that did not offer this capability. It works perfectly.

I connected a monitor (1440p at 144hz) with a mini DisplayPort input to an RTX 3070 with a DisplayPort output and it has been working flawlessly for 2 years, and the FreeSync/Gsync functions properly.

The purchase was made in order to connect a Macbook Pro to an external LG monitor. No disconnection and value for money the purchase.

It does its job just fine, the g sync works properly. 2m cable, what else do you want.
Edit: It broke within two to three months.

I bought it to connect a Thinkpad 430s to an LG 4K monitor.
It connected easily and achieved a 4K resolution at 30 Hz, but I didn't try higher frequencies in 4K because my laptop's graphics card can't handle them. It works fine at a lower resolution of 2540 Hz, that's as far as I tested it.
I didn't experience any disconnections, etc., I am satisfied.

I bought it based on the positive reviews and I can say that I was highly satisfied. I wanted it to achieve 4k at 60hz and I had no issues at all. It definitely worth its money.

I bought it to connect a RX280X GPU to a 27-inch monitor to send a signal at 144Hz. It worked without any issues on the 144Hz monitor.
