12 PCS Zip Repair Kit, 3 Sizes Instant Zipper Repair Kit, Extension & Fixing Zipper Slider Replacement for Luggage, Backpacks, Jackets, Zip Repair, Replacement Zip(Black)

Terrible, no instructions and doesn't work in the end anyway. Just very bad product. I've asked for a refund, which was granted of course, but funny surprise, Amazon said I didn't need to return the product!! I5 seems even they know it's useless 😂

Doesn't come with instructions and the the zips aren't labled so you spend ages trying to workout the difference between them, after half an hour I finally manged to figure it out and it didn't work

These work great on jackets but they are useless on trousers which is hat I wanted them for. The fly zip has worn in one place and the sipper became detached. The problem is that this kit cannot repair the bottom of the zip which is undone and sewn in to the trousers. It can fix the top part but with the bottom unsecured it will just fly open when stressed. In summary these are excellent when the zip closes bottom to top as in a jacket but useless the other way around. Hence four stars.

Love the idea but these don't work.

There are no instructions with these repair kits so I have no idea how they are meant to wok.Sorry this is a negative review, but there's nothing else I can say.
