Review on Robinair LD3 Air Tool Fittings by Jonathan Arroyo

I used the older brother for this detector and it works the same without the extra bells and whistles. Adjustable sensitivity allows you to pinpoint the source of the leak. I had a bit of trouble adjusting the sensitivity initially, but I was a bit impatient with the button press. If you repair and diagnose an air conditioner, this tool is a must have.
