I have very similar cat trees before, and this one is 

pros
- budget friendly
- can be adjusted to the lowest height compared to other existing products
- a thin and tall design. less obstructive when it is placed at home

cons
- so far the most flimsy 
- not very securely pressing the ceiling 
- color is a darker grey. I personally prefer lighter
- better if contains sisal rope scratcher (u can DIY) 

Bottom line: 
I've moved to a low ceiling condo and all other products on the market do not fit. Plus my cats are small and lightweight. So this is a reasonable buy for me at this price range. If you have a bigger cat or higher ceiling, my suggestion is to look for a more sturdy design (e.g. the bottom design is wider than the upper or contains two poles. Having sisal rope scratcher is a bonus.
