Like it very much

### ⭐⭐⭐⭐⭐ Top quality for aquatic needs and cheaper than garden centres
*by A***. on September 1, 2025*

Easy to use and it’s very strong it’s been a while since I applied it to a pond waterfall and it’s sealed it nicely and the water flows better with it saved me getting it welded. Strong adhesive for jobs that need it would use it again if I ever needed to.
