There are several of them, not critical, but there are.
1. The TV tilt lock is rather weak, the tightening mechanism has a bolt, which is protected by turning with a square shape at the cap, which immediately licked off, otherwise it is impossible to hold it when tightening on the other side, there are no grooves for a hexagon or a screwdriver.
Also, the tightening perfectly holds the given slope in a fixed position. However, given that, according to the design of the bracket, the handle for lifting the TV is at the bottom, and you lift it and push it forward, then the tilt can be easily knocked down, but not returned.
2. Complete set. A bunch of all sorts of screws were poured for all occasions, like a plus, but the number and their type did not match the specification, and the most necessary ones, as always, are one type and it does not fit (more on that later), the washers did not fit the screws perfectly (the inner diameter is too large washers). Well, the most incomprehensible thing is, when you hang the rails attached to the TV on the bracket plate itself, then there are not enough screws for its strong fixation in length, i. E. they protect against falling, but do not fix. When the TV is on, everything is ok. But when you start pulling or pushing the handle, a terrible backlash occurs, it’s very scary, no matter how it falls off. Changed to others and put a gasket, the problem is gone.
3. The dowel holes are quite small. The kit included dowels 10 * 80, and the screws from them crawled into these holes. But they seemed to me not super reliable, I bought Fisher 10 * 80 dowels. And now their screws are larger in diameter, they no longer crawled through, I am silent about dowels with a diameter of 12 and 14 mm, I had to drill them out.
