These look more sturdy in the picture, they are molded plastic from one side, hollow from the other. The stakes don't do much to hold them sturdy and the slightest wind from a storm makes them sag. I live in FL and I am sure when it heats up they will be even worse. They are also very small in scale, and won't even make it around my outdoor HVAC or Pool pump. I was hoping to hide one of them at least, but No, just won't work. Definitely NOT worth the money spent. 

Pros: none
Cons: Poor Quality. Cheap, like a dollar store quality.
