The repair has worked very well, though we discovered the tension adjustment can be a bit touchy. Once we got it set correctly though, it's worked perfectly. In a related discovery, applying 'Chapstik' lip balm to balky zippers that stick or pop open *may* allow them to work normally again. When we had first installed the replacement slider, the zipper worked poorly and wouldn't close consistently. But after sacrificing a tube of Chapstik to the teeth, normal operation returned.
