Works good!
It works well on looping back the 12 strands of fiber in an MPO connector. No more having to put multiple patches in to return all of the strands when testing out your MPO cable. Works great!

Works!
Used it today and it worked like a charm! The quality is fine, it feels like it will not fall apart after a few uses and does what it is supposed to do, return light! Great addition to my fiber/network toolkit!
