Almost Perfect
This electronic stethoscope is much more sensitive than the conventional manual stethoscope I used before to look for sprinkler valve leaks. Note that it is a contact microphone only. That means that the probe end needs to be in contact with a hard surface on the valve, pipe, or automotive part being investigated. It is purposely insensitive to air transmitted noise to cut background noise. You should turn the volume down while you are making contact to keep from having a loud pop in the earphones. There are two volume controls: One on the earphone cord and one on the unit. Make sure that neither is turned off. I dropped 1 star for two reasons: First, there was no 9V battery supplied, as the product description and package content indicated. Second because the LED does NOT indicate the signal strength as the product description claims. It appears to be nothing but a very bright on/off indicator. Despite these minor discrepencies, it is a very useful product and comes in a well made protective carrying case. I used the stethoscope to figure out which of two valves next to each other had a leak. Even connected to the same supply pipe and only inches apart, it was easy to hear which one had the leak.

Not what I thought
I was trying to hear an air leak in a truck system. This is more of a contact unit. It dous not "hear" ambient sources. The volume is touchy. Didn't really solve my issue.

Works as advertised
A unit that does exactly what they claim. Unlike a stethoscope, this unit has an amplifier built in, so it's easy to hear the sounds. It does the job.
