I can’t complain, works great.
I purchased this in 2023 and finished the tube in late 2025. It never once failed me as far as drying out or the tube bursting. My only suggestion would be to have a way to make it come out in a thin line like caulk. I use it to glue gaskets that fit in a tight spot. Buying another one now. The gaskets stay in place but I can remove them pretty easily if they need to be replaced. Dries overnight without a problem.

Worked For My Purpose
This product was recommended for filling a crack in a refrigerator, so I used this for that purpose. I used it while refrigerator was running. Dried fine; dry time unknown. Worked for that purpose. Not a fan of the shine when dry since the repair sticks out, but it worked.

From Yikes! To genius.
Destroyed some necessary styrofoam in my KitchenAid refrigerator. Yikes! This silicone covered up a world of sin and made me feel like a genius. Thx

works
Another reviewer stated that the product dries up in the tube after one use. If you re-cap using the original cap, it will last longer. The attachable nozzle can be cleaned (when the silicone is dry, it peels off from the inside of the nozzle). I tightened the cap a little too much and it cracked, but I used some of the silicone on the outside of the cap to help seal it.. I've used it 3 times since buying it and it's still working fine.

Product works very well.
This worked very well. I repaired my refrigerator cracked with it, and it was seamless and unnoticeable.

Does the job
Holds securely and has allowed me to keep using my coffee drip basket for years after it broke. The tradeoff is that it takes a full day to cure, plus it's opaque and picks up stains. But if you aren't worried about aesthetics, it's a good value.
