*by L***N on 5 March 2026*

I’ve been using this leak detector for a few weeks now and it’s been super reliable. The sensitivity adjustment is great — I was able to track down a small R410A leak that I probably would’ve missed with my old detector. The screen is clear and easy to read, and I like that you can mute the alarm when working in tight or noisy spaces. It feels solid and durable, and the battery easily lasts through a full day of service calls. Overall, a really good value for both HVAC work and DIY use.
