Exactly what I needed
Late review for honest review - This stuff is great! Already fixed a few horse tubs, bird bath and shows zero leakage, excellent purchase. It’s clear as it dries. Durable and saved a lot of things from the trash!

Application was easy.
Appears to be as advertised. Application on gutters was easy. I will have to wait until it rains to see how it holds.

This works
This worked and did what it needed to do and my apartment there was this hole by the bathtub where roaches would come and I put this on the hole and I have not seen roaches ever since so I'm glad that I bought this and plus buying this saves me from having to have the maintenance man come in I don't like to have maintenance come in when I don't have to

Easy to Use and works as described
I’d been trying to fix a leak in my birdbath and was fed up with the mess that the regular waterproof silicone made. It’s so hard to push the middle of the tube up to dispense unless you have a caulking gun dispenser. This Flex Caulk is so easy to dispense and worked perfectly

Not usable. Wouldn't come out of tube. Dried up.
Not functional, dried up.
