Great value product that works!
This is a great product. It fixed an outdoor burst pipe and saved me a visit from the plumber.

No more leak
Worked an absolute treat. Had a leak on an old iron pipe that couldn't be replaced and having tried various repairs, this is the only one that really worked. Once in place, it goes harder than Chuck Norris

Closed a 5mm hole in a copper pipe nicely
Did the job nicely, on a 5mm hole blown open in a copper pipe in an outhouse when I was away during freezing temperatures. You have to keep molding the putty onto and around the hole and pipe as it slowly hardens, as it doesn't seem to cling to the pipe for a while, but does so eventually as it hardens. The FiberWeld stuff on top of that is brilliant. I used it alone to repair a smaller leak in the same pipe a few years ago, and with the putty as well, this saved me a hundred quid or more to call out a plumber.

Item unusable/ Replacement Very Good
Original: This product was unusable. On removing it from its packaging. It had already cured and was rock hard. I cannot give it any more than a single star, but this is not a true assessment of the product, as it was clearly faulty. Replacement: Worked well, sealing the pressure leak as required. Note, that this product is very messy, just be prepared!

Permanent repairs are possible with this kit.
I tried several other products to temporarily seal a leaking pipe near our radiator. This is so good it’s a permanent solution. Easy to use and sticks like you won’t believe. Fabulous product.

Part of item didn’t work properly
Product that I received looks like stored or transported incorrectly because one of the components (cold weld) has been activated and doesn’t mix properly with hands. Overall this kit not work as I expected.

Strong seal, but may not work for large pipes.
Bought this for repairing broken pipes and sealing leaks. What I like • The cast is easy to apply and molds well to the pipe, providing a strong seal. • Quick-drying and durable, ensuring long-lasting repairs. • Works on various pipe materials, making it versatile for different plumbing issues. What could be better • The application can be a bit messy if not used carefully. • It might not be suitable for very large or high-pressure pipes. • The instructions could be clearer for first-time users. Bottom line: A practical and effective solution for pipe repairs, but may not work for all types of pipes. Perfect for DIY repairs and temporary fixes, but consider professional solutions for high-pressure or larger pipes.
