Slightly fiddly to get working but once you get the hang of it, it works really well. There's a clear guide in the photos to identify the correct size for your zip which I highly recommend you use as this turned out to be accurate in my case. I didnt try a cheaper version as they all had bad reviews, this one didn't and was the right choice.

Acheté pour réparer un sac de golf à fermeture étanche. J ai su la refermer après de nombreux essais mais n est pas aussi efficace que celle d origine. Disons que ça permet d encore utiliser la poche mais pas de manière intensive.

This is a very hefty zipper and the concept is very easy to understand. I found it a bit tricky trying to engage both sides of the zip which had a block end. After several attempts I was successful and the zip closed. Unfortunately, as I opened the zip, the teeth failed to die gage and the zip broke. The zipper itself was not at fault, but the integrity of the zip failed. Need a new tent!

Compré este artículo para reemplazar las cremalleras de un saco de dormir que estaban rotas. Requiere un poco de paciencia, pero es fácil de instalar; problema resuelto. Artículo de buena calidad.

Bought to try to save my plastic zippered work trousers when the cheap plastic slider broke. Works brilliantly, good instructions plus excellent 'how to' video on YouTube. Easy to fit, fully tightened job done. Full metal build and comes with everything needed. I did measure the zip width prior to purchase to ensure I had the correct size. Bit expensive but when these trousers wear out I'll remove it for future use.
