I was skeptical about using a refrigerant leak prevention product but I decided to try this one out .Based on my experience, it really works! My air conditioning system no longer leaks and I don't have to constantly refill it. The best thing about this product is that it's AUTOMOTIVE-BASED and tailored to work specifically with automotive air conditioners. The only downside is that it may not work for larger leaks, but for small to moderate-sized leaks it's definitely worth a shot..
