### ⭐⭐⭐⭐ Initial Feedback
*by R***R on September 7, 2023*

It is too early to comment on how well this product fixes the leaks on my backyard pond as It is only 2 days post installation. I’m commenting now to help others as they consider this product who may be concerned about multiple reviews stating how messy this product is. This was a concern as I considered the pros and cons of the purchase. This product is no more or less messy than any type of adhesive caulking I have ever installed. Of course if you are not careful it can be a problem. Simply take your time to get the nozzle cut to the volume you want to apply and then run your bead accordingly. I found the info online adequate to understand how to prep and apply the product. If the product performs as specified I wil change the review to 5 stars.
