## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent for small leaks
*by R***R on September 18, 2024*

Worked like a charm for me. I had a very slow leak and it sealed it perfectly

### ⭐⭐⭐⭐⭐ Does what it should
*by T***R on July 12, 2025*

Easy to use

### ⭐⭐⭐⭐⭐ A real problem solver and money saver!!!
*by M***A on June 29, 2025*

Our air conditioning system was not keeping up with the heat and we were spending a fortune on refilling the refrigerant every friggin' week. My husband purchased this on a whim, and, miraculously, problem solved. Our air conditioning actually gets too cold now. Recently, my son had an issue with his air conditioning, so I sent him this leak sealer to see if it would help. Sure enough, his air conditioning stands up to the summer heat with no problem, whereas previously, it was barely able to cool the house down. This is great stuff!!!
