I ordered this after I read the other reviews. Following the advice of previous reviews, I checked this item directly with Armacat - they now wanted over $230 for this item, and with ebay - the lowest price was $130, so Amazon still had the best deal. I was a little apprehensive about putting it together, but when I considered the savings over buying one already assembled from my local pet store, I decided to try it. I figured if I can put together Ikea furniture, I can do this:)
It arrived quickly, and was simple to put together - I completed it in less than 20 minutes. One tip: when using the double sided screws, don't screw one end in completely and then attempt to screw in the other side. The screw is too short for this to work. Instead, scew one side in part way, then the other, and twist the leg to make sure they are tightly secured in place.
My 3 cats LOVE it - there is something that suits each of their personalities on there. My 11 month old was climbing it as I was trying to put it together - he just couldn't wait to try it! Of course, he liked the box it came in too.
The only thing I found surprising was that the "tunnel" on top is pretty small - only a kitten could really fit inside of it. Overall, I'm very happy with it and would not hesitate to order from them again.
