The A-frame sidewalk sign is working well for our church. It is being used mainly inside the building in a lobby, so I can't speak on how it might do in the weather elements (standing against wind).
It is light weight and easily portable, yet sturdy when extended for standing. The hinges are a bit difficult, in that one side "catches" when extended and we need to fiddle with it to get it in position so it can extend all the way.
But it is meeting our need and we are satisfied with it.
