IT WORKS!
Just bought a new house, and half of the plantation shutters had one or more connectors broken.  Called around, and no one had a fix, just offered to give a quote for replacing the shutters in their entirety.  Watched a video on the shutter repair kit, talked to Harry (very helpful), and ordered 2 kits.  Repaired the shutters in two rooms before I ran out of inserts.  Just ordered more.  They do the job.  It takes a little practice to minimize the occasional breaking of the inserts, but I got good at it quickly.  Highly recommend this product.
