Just set up eight of these to replace wooden garden boxes that had rotted out.  The design is simple and easy to put together.  They can't be configured differently and are limited to the square shape.  This is all we wanted but I could see it being an issue for some people who want longer rows.  

There is some really good information that comes with the kit on how to start your garden bed.  I wasn't expecting anything like that but it was a good read and I'll follow what it said.  

We haven't grown anything in them yet but they were easy to install and the instructions were not difficult.  Once assembled, we could move them without any issue because they were so light.  This made it a simple process to configure the garden.
