Overall the product is excellent. The screws holding the top cable management bits in were done up way too tight and would not come out. The bottom cable management piece is a clunky design and one of the bits that is supposed to hold it in broke off. Run the cables before you put the monitor on the stand.
The arm is sturdy, it says 30" monitor, but it is comfortably holding my 34" Ultrawide (6.7kg) with no issues.
