Unfortunately, I can't answer that - I only had the stand for 1 hour and it was too high [TV position].
My impression of the part was stable I decided to use a wire model because it rests on the TV in two places and the VESA holder rounds are held together with leather straps, which holds it securely.

Yes, it is independent of the model as far as the mounts are concerned, as they all follow the VESA standard, so you can mount LG/Samsung/Sony etc. etc. without any problems (I hung an OLED65GX6 on it). With the stand, the weight of the TV is more decisive.
