Easy to put together.  I ordered 3.  After I put them together I realized one of the corners on one didn't stay snapped in place.  It looks like it's warped in one spot so the tabs won't snap into place securely.  If I put dirt in it it will just flow out of that corner.  Unfortunately in trying to get the tabs to snap back in place I broke one of the trellis poles...these are plastic after all so not as sturdy as I'd hoped. They look nice for plastic but are overpriced.
