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

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.

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

Absolutely brilliant product
Amazing stuff I had a leaking hot pipe under the bath repair man couldn’t get to us for a fortnight so I wrapped the pipe in this it held the whole fortnight an probably would of lasted longer it was that solid the repair man ended up having to saw the whole pipe off oops so does what it’s advertised to do I’d definitely buy again and it was cheaper than the local diy stores so I was really pleased

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.
