These are okay.  I will say that they don't hold as many plants as you would think...so make sure you plant something that is going to crawl to fill in the gaps.  Also, I had to glue in some 1x1 pieces of wood in the insert so it would quit tipping to one side or the other of my rail during high winds.  The color is great and they seem to be very durable.  All in all I am pleased with my purchase
