Example Input: This playing mat is awesome!!! It is thick to provide enough cushion. No funny odors. easy to wipe clean, which I love! It is foldable, so save some space and I don't worry about my cat running on it and scratching.
Example Output: 5

Example Input: I have a pair of compression socks that were $25 a piece and I can definitely tell the difference. These are quite thin but they'll do until I am back home and can get my good socks (currently on a travel assignment).
Example Output: 3

Example Input: There are some design flaws like the ramp's black rubber goes loose easy, and the rake gets stuck at the dirt bin on manual function, But otherwise, The Automatic function works well and does it's job..... The Plus is that it saves me time in manually cleaning the dirt as opposed to the non automatic litter box.... For some, The flaws might be a big issue, but these does not bother me much for as long as the main automatic function works as intended.... If ever this machine breaks, I definitely will try the other brands next time....
Example Output:
