I'm usually stingy with 5 star reviews but in this case it's true. The physical feel of the device is solid and well made. The clamp function is accurate when tested against a known current. So far I like everything about the Klein CL390, including the price. What really got it 5 stars is that the instruction manual was thorough, clear, technically correct and clearly written by someone who is fluent in English.
