Very nice steps. my dog learned to use them after about 1 hr of training trying to get he to go up and down about 20 times.  To me this is very quick.  I love the wood and the carpeting on the steps make it very comfortable for my dog.

Cons  I would have given 5 stars if the installation didnt involve glue and dowells.  Other than this minor downside, its easy and straightforward to put it together.
