This is a somewhat classy, more unusual garden decor device. It was a little weird to put together, especially as I had so much hardware left over afterwards I really wonder if the right instructions/hardware set was sent w/my item: Maybe the hardware included belonged to a different sundial. But it seems sturdy. Of course, it does have to be placed on as flat a surface as possible, doesn't need to be concrete, though, as I have mine sitting directly in the dirt high up in the yard (I have a sloping landscape).
