Review on 🔍 High Accuracy Refrigerant Leak Detector with Indicator Light - Instant Halogen Gas Leakage Tester for HFCs, CFCs, R134a, R410a, R22a - Ideal for Air Conditioning and HVAC Systems by Justin Frazier

worked great the first time, now the buzzer won't go out. It is very difficult to see the LED in broad daylight, so the tool has become ineffective. The manual does not specify the manufacturer or what to do if warranty or service is required. Also, there is said to be a 1-year warranty and free replacement repair without the ability to process this. I can go back to Revain but the price has gone up so I have to play another $$ to try again. Does anyone have an email address or link for a replacement? I will update the review if someone contacts you. Seller 5/22 replied, asked a few questions and sent replacements. So far, so good. It doesn't matter who makes your tool, what matters is accuracy, reliability and warranty. I have had high end diagnostic tools fail and if there is support it is a good investment. The leak was found pretty quickly!
