The price was right, we got free shipping and it was delivered in 2 days. It was easy to put together, but we did modify it a bit. Instead of the enclosed cave on the 2nd tier, we moved it to the first tier. She doesn't use the cave thing anyway, and it provided more room for her to jump up & down easier. 
Also to stabilize the tree we used corner brackets on the top tier. It wasn't stable enough on its own. All in all we are very happy with the product. It's nice & tall, & the tiers are covered in a very soft faux fir. We drilled some holes in the tiers and secured some toys up there for our cat too. Good product, good price.
