I have to say I absolutely love this product.  There is one glaring flaw, but first I must say this brilliant device is unique in its ability to go from Ddrt to Srt completely seamlessly, and MID LINE.  I really can't say how much I love this device, just that it has changed my climbing style completely and it is way less work/effort than my old systems.  
That said, why is this product not made with stainless steel?  I wore out my first unicender in one season.  They will repair it for more than half the cost of a new one and at just over 300 dollars it simply will not do.  Please make this out of stainless steel soon Rock Exotica!
