I have it here for a few months on a 55-inch LG.
Very sturdy construction, easy installation, and even on a TV that normally the base that suits it is of a different type that is like a "rectangular back"

With a 55" television (2018 model), it is not stable enough, it feels like it's bending and easily loses its "alignment".
I would say that in terms of construction, it may be suitable for smaller TVs than those stated.
I should have bought a more expensive and better stand from the beginning, but unfortunately, they only had this one on the site where I purchased the television.
