What for
I bought this a long time ago and I can't remember what for, but I do remember it did the job well.

All good so far
Used this to glue the washer to a jumper plate in a tap - the retaining screw at the base of the jumper plate had sheared off so nothing much was holding it in place. Seems to have done the job - tap is working well - only time will tell if it has staying power.

Very good product
Because is safe Iโve solved my falling off shoes problem. I have number of shoes that jus hold to the heel very badly, and keep falling of all the time when walking. So 2 stripes of that silicone fixed the problem and I can use my beautiful shoes finally :)

Excellent and long lasting
I used this to glue a handle back to one of my mugs and the handle has stayed in place for more than 2 years.

Very good quality. Doesn't dry up while inside its tube.
Great quality silicone. I use this to attach decor to my home's exterior stucco. Unlike other brands, this tube doesn't dry up over time like other brands. It stays malleable for years. Once in a while I have to pull off a silicone cap that develops underneath the plastic cap. Easy. No problem.

Great
Nice sealant that I am not able to find locally. It does take 12 to 14 hours to fully dry, so keep that in mind when you are working on your project. You cannot touch it during the curing time.
