Review: Quick Response - This refrigerant leak detector clearly states that it is compatible with A2L and flammable gases, which gives me peace of mind. During actual testing, it responded very quickly; as soon as the probe neared the leak, an audible alert sounded immediately—no waiting required. The handle is comfortable to grip, and the probe is very flexible, allowing it to reach into narrow gaps for detection. When I used it to check for leaks in my home’s air conditioner, the results were immediately clear. The screen display is crisp, and combined with the audible and visual alarms, I never miss a signal even in noisy environments—the design is very user-friendly.

### ⭐⭐⭐⭐ Refrigerant Gas Leak Detector
*by B***. on May 6, 2024*

I'm an older seasoned automotive technician, I'm reviewing this product based on my many years of experience in the field using high quality tools and equipment. Digital Halogen leak detector used for detecting freon leaks in A/C systems. Made of plastic with flexible wand for reaching tight places in A/C systems. Seems to work okay, put the wand near our freon tank and it detected the presence of freon, but unsure just how small of a leak it will detect. I'll update this review as needed once the A/C season is in full swing. Price point is considered high for this item.
