One of the best epoxy glues I have ever used. Cures fast enough to avoid frustration, yet gives just enough time to set the parts right. The only small issue is the fact that it is relatively difficult to squeeze out larger amounts of both the epoxy and the hardener through the spouts; in such case, I just unscrew the top altogether and pour the amount required straight out of the bottle. In any case, I highly recommend this versatile glue.
