This is a fantastic product!  Great pricing, sturdy and easy to assemble.  My only suggestion for others is to use some rubber cement to keep the 4 plastic end caps in place on the 4 bottom base brackets. Certainly nothing at all crucial to the operation of this product - merely an aesthetic suggestion.  Otherwise I heartily and highly recommend it.  It’s not often that I find a product online which is this well made and which fully functions as it should.
