### ⭐⭐⭐⭐⭐ Great product
*by M***A on 10 May 2021*

This is second time I'm buying it as need to move old one from item I used and replace item and can say till now no drop went trough while before there was leaking and first silicon after some time release on parts. It's good quality.

100% brilliant stuff. Used it on my caravan windows after they delaminated. This stuff is absolutely fantastic.

### ⭐⭐⭐⭐ Did exactly what I wanted
*by J***N on 15 April 2022*

Used to stick some lumps of rock together to make a shrimp friendly hiding place, left to dry for a week and its solidly stuck together. Super glued java moss to it so very pleased with it (and myself). Used it for a couple of other small jobs and by chance seem to have hit on a way of stopping the nozzle blocking up with cured silicone as it arrived with no nozzle cover. I cut the finger off a thin rubber glove and used clear medical tape to seal it tightly to the nozzle. Probably not news to some diy-ers but thought it worth a mention as I have thrown out a small fortune worth of sealants over the years that have dried back into the main tube.
