Item has a lot of good features, but screen is very hard to read since it is so small and the inductive pickup hole is too small for most of todays negative battery cables. Tried it on 3 different vehicles and just could not get the clamp around the cables. I will keep it though as I am sure I will get to use it someday. Did not buy the unit for the ohms and such since I have a fluke meter, just thought it would be nice not to have to disconnect the bat cable for milliamp draw test.
