It is portable and very convenient. I live in a small LA Bungalow and it is perfect when I bring my laptop home from the office. No more setting it up on the dinning room table. Be very careful when putting it together. The picture is very small and you can easily miss putting a part here or there and then you are taking it apart again to add the part you missed. Took me about 21/2 hrs to put together because of this. The part of the caddy that holds the laptop is not as sturdy as I would like. It wiggles a bit and can be annoying. I wish it were tighter. Had I seen this in a store I probably would have bought it anyway but, I can say that I an not completely happy with it. For what it is.... it works for me.
