On the market, there is a rating of 4.8, apparently the reviews are custom-made. The bracket does not meet the stated technical requirements. TV 20 kg vesa 300*300 cannot be installed strictly vertically, it sags due to flimsy metal even when the angle is set to a negative value of -2. As a result, the TV hangs at an angle, and this is useless. Will have to buy another one.
To showcase the product's features, I have added some photos to my review.
