Great product, purchased mine on June 1, 2014 and still working pretty well. Things I would improved one, plastic clips which hold the corners together.  I've had several already break.  Company sent me new ones right away.  However, the last one that broke I did not have the time to be bothered so I used metal flat mending plates and it works better that the corner plastic clips it comes with.  Also, after almost 4 years one of the panels is bowing out a bit and I'm experiencing  soil loss.  Wish they sold a trellis kit for these.
