[Q]: I like these stair for my chi, he is only 5 pounds and this stair is easy for him to climb. plus they can easily be carried to my motorhome so he can get on the bed.
[A]: positive

[Q]: The brushes have good quality. They are soft, strong and easy to clean. It is good to have a lot of different brushes. As a beginner, I'm very happy with my purchase (I know they are all useful, I just need to learn how to use them all).
[A]: positive

[Q]: The advertisement did not state that assembly was required, so I thought the only thing I would have to do is put on the wheels. I am 77 and do not like assembling things when I get them. Second, there was a part missing and a friend of mine had to make one so I didn't have to wait. Third, the second to bottom draw is splitting and they must have used green wood on it. Happy? Not in the least and I would never buy another product from them.
[A]:
negative
