### ⭐⭐⭐⭐⭐ Sticks very well.
*by R***. on April 22, 2026*

Works good, I use it to repair my hunting blinds. One is still good after 4 years of being patched.

### ⭐⭐⭐⭐⭐ Nice
*by H***N on May 20, 2026*

Nice

### ⭐⭐⭐⭐ Great product but don’t believe what you see on tv
*by S***Y on September 2, 2025*

I purchased flex tape for a few different problems I had. The first was a leak in my water storage tank. The other was a crack in a pond. What I liked: ✅ Quality: very strong and sturdy material will definitely hold up over time. ✅ Seal: when used on a completely dry surface and smoothed out creates a water tight seal. Almost impossible to get off. What I didn’t like ❌ not as seen on tv: this product is shown to be able to apply on an active leak and still seal. You won’t get a perfect seal this way and have small leaks. Only apply to fully dry areas. Same goes for clean smooth surfaces. ❌ heat and weight weaken: if this is used where heat builds up and any sort of weight is applied at the same time it will loosen the adhesive. Overall I do like the product to patch things up but don’t use it like you see on tv. Fully clean and dry the area first. If applying to a surface with texture know that water can travel in the small crevices and still leak out.
