Review on 🌬️ Leak Saver: Direct Inject Dry A/C Moisture Remover - Premium Solution for Up to 5 Ton Systems - Transforms Moisture into Synthetic Oil - Trusted by HVAC Pros - Made in the USA by Raymond Gray

There was a problem with entering the system. Make sure you tighten it fully with pliers and somewhere wearing thick gloves to protect your hands from frostbite. It didn't work the 1st time, the company sent another 1. They stand behind their product. I can't say it works because I don't know how big my leak was. Make sure you buy the desiccant injection first, then put the UV detection seal.
