The tower is a good size for when the butterfly flies around. And adding plants. It is well made, easy to unzip and zip the door, which is large. I added a poo poo platter which is easy to clean and gives a little more stability. The unit is easy to move around. I had one net cube which was housing chrysalides which I mistakenly thought would eclose in spring. I rapidly studied up when the first one popped out. Trying to give the swallowtails a comfortable, though brief and "not what they expected" life. I am a newbie to butterfly care. They are bringing cheer at a dreary time. 2/2022
