This trellis is stronger than you'd think. It supports heavy plants well and holds up to weather very well. Its flexibility to adjust the shape to your needs is a great feature. It also makes it easy to collapse and store away! I used the Garden Links in a zig-zag fashion in a planter bed to maximize support for tomato plants in a limited space.
Work very well for combining to create a trellis just right for the space that we needed to fill. They come with plastic connectors but we found they were not enough for our needs so we supplemented them with some garnden twist ties. We have four panels connected two wide a two high and were able to create a perfect fit.
I purchased these tomato cages to replace the rusted wire cages we had been using. They held up well through the first year's use in the garden, and seem to be in good shape to use in the coming years as well. Using one cage for a full size tomato is a bit stingy on the support, but adequate. Now that the veggie season is over, they are deployed around the yard protecting valued small shrubs from deer damage (when combined with netting). Folding flat for storage is a real plus - if I ever get around to storing them!
