Never have any issues with RSBTR. Amazing service and quality.
Great product to use in conjunction with the 1.43 dyneema for my quilt storage cube.
They work great, easy to sew through and install. Opens and closes smoothly.
YKK components are the gold standard. The #5 uretek is perfect for larger products and tents. I like the #3 for small tarp applications or for anything requiring less overall strength. These zippers are water tight, they sew in very easily and straight.
