Was fairly easy to assemble, but the small tabs to make it "click" into place for the pickets? The holes in the base, that you slide the pickets into, are too large and the pickets to not "click" and hold. I don't expect anyone to be trying to pull them out from the top, but if they did, it would be easy as they are loose. I am using this fence mainly as a visual deterrent for the dogs to stay out of my flowers. For the it will be perfect.
