as the nets and products? its good, very stretching, so I recommend making it hella tight before you put squishmallows on them
they come with zero instructions. The hooks don't properly fit the plastic things that go in the wall, so I suggest just using the thredding on the hooks as it works probably better.
personal things I did wrong was forget what sound a stud is and what sound is a hollow sound. and I also did put it a little loose, so I had to pull some of the netting and make it tighter on the hooks, otherwise product is good
