messy
I was rather disappointed with this product, while it has the added convenience of being watered just once , it takes away by the fact that the adsorbent jelly takes up too much space. After filling to the specified level it starts spilling soil while it grows which was quite messy and annoying to clean up from the windowsill.
My cats are not super interested with this but then again this is good for their diet and not meant to be a game, after a few days they have successfully eaten most of it.
