Have Patience
This stuff is really good. I was a bit dubious at first as it’s quite loose when it comes out of the syringe and stays the same on application which, to be fair, helped me out. It stayed sticky for hours afterwards causing me to think it isn’t set properly or my mix want correct. However after leaving it overnight it solidified into a really strong bond which hasn’t budged since. For reference I used it to repair a broken weld on a bar stool frame.

Best adhesive I have tried.
I have now used this adhesive several times especially for cutlery used in a dishwasher. It is excellent and so far I have had no repaired items fail the dishwasher test!

Sets rock hard for a solid strong bond
Bought this epoxy adhesive to glue magnets onto my front door letterbox which was rattling during recent high winds. The magnets, now securely in place, allow a firm grip of the outer flap without the postman noticing the additional effort required in lifting the flap for mail. The epoxy resin fixes metal to metal and is completely cured within 12-18 hours. I had to take care that only the magnets were glued to the metal parts of the letterbox as any overspill would have resulted in the letterbox being totally sealed as this resin sets rock solid.

Excellent strength hold
Used for a work project, really simple instructions on the reverse and worked perfectly as intended.

Excellent adhesive properties
Needed to fix some shock connectors on an Eames chair. So far they have held and i tested on a temporary fibreglass piece and rubber and cannot for the life of me remove them - so have complete trust that this will last a lifetime.
