Review on Optimized Elitech WJL 6000 Refrigerant Condition Detector by Lawrence Allison

I liked it, a good level of sensitivity. Others may have encountered problems as closing the tip activates the sensor. Don't tap the surface and it will work great. Definitely exceeded my expectations for the price. The size is good, the neck is very flexible but keeps its shape. I took off a star because the battery cover/bracket installation is fairly cheap and clumsy and difficult to assemble and I was afraid of damaging the wires when reassembling. Compromise for the cost I suppose. I can definitely recommend this device.
