This "necklace" is incredibly robust and the workmanship is first class. He can't physically lie flat without 5-10 pounds of pressure, and he won't stay up if you're weak. You have to loosen each individual limb and unfold the legs that form the physical stop so each individual limb has the extra millimeter it takes to fully expand to 180 degrees, not 175 degrees. This only solves one of their problems, and for some, the second problem may not be as important. The links fit together so closely that they do not support smooth chain movement, instead creating clumsy and unpredictable link chains that do not bend and cause abnormal kinks. Sure, I could go through and drill every hole in every link so it has some extra room to move, or I could buy another product and not waste time fixing it. Upgraded to 2 stars only because the material actually feels good and durable even if there are no manufacturing tolerances for performance.
