Love the aesthetic of these hooks.  The screws that come with them are not very long.  They would likely work if you were putting them into a wooden plank or something along those lines.  I was putting them directly into the wall/stud so I needed something longer and more sturdy.  Bought my own hooks and could only get silver so now I'm trying to find a paint pen to match the flat black of the hook which has been a challenge.  Overall happy with the hook and seems sturdy with the longer screws.
