### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Silicon

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.
