- This is a good product, the quality is not the best however it is in no way shabby and it does represent the price point.

- Item does wobble but  will not fall over if cats are on the top. I used a small L bracket to secure it to a stud in the wall from the second level and it does not move at all now.

- Easy to assemble. Only took about 10 min when taking our time.

- Took a week or so for our cats to start using it, but it seems it mostly depends on the location and the personality of the cats as to whether or not it gets used. I think most cats would enjoy this product though.
