Shipping was fast but not packaged very well. The bottles had broke through the envelope it was shipped in. One of the bottle lids was broken, luckily there wasn't a leak. Unfortunately the product didn't work for us. It was worth a shot though!

didnt work. i dug the insulation out and the tiny drip was fixed with marine caulk

Not the stop leak problem. Crack was too big. I will have to call a service company. Will continue to buy my spa supplies from them. Best people I have dealt with.

Did not make a difference in my slow leak.

I was losing about 3 gallons a day out of a 260 gallon spa. I had previously searched for the leak removing insulation but it appears the leak was in piping in the lower portion that I couldn’t find. As the spa was inside and damaging interior walls I put a diaper underneath with a drain but this was a pain having to add water. I finally tried the spa leak sealer using 2 doses over a few days. Leak is now down to less than a quart a day. Hoping the seal lasts.
