I love these, they are very smart looking and the perfect size.  Even filled with soil they can still be moved, maybe with a bit of tugging.  Not all that easy to get together at first, reminded me a bit of a Rubik's cube and you have to follow the directions EXACTLY (not my strong suit at any time), but once I got the hang of it it was not too bad.  I now have 2 cherry tomatoes in one of these boxes and they will do quite well I'm sure.  I did put some screening over the hole in the bottom.  Water can also drain out on the sides at the bottom, so drainage has not been any kind of a problem.  Highly recommended.
