Review on 🔍 Certified AC Pro Car Air Conditioner Stop Leak Detector Kit: Glasses, UV Pen for O Ring and Hose Leak Detection - Professional Grade (438) by Will Anderson

Absolute rubbish. The light is so dim you have to be within an inch of it to see the UV dye. That and the light is already intermittent if it wants to stay on or not when you first use it. It's cheap plastic, painted to look like metal. Spend a few bucks more and get a big powerful UV light, it works amazing. I am much happier with another UV product I have purchased and wish I had never purchased this one.
