Dang near perfect
Works as described. Would get 5-stars if it came with any form of storage container.

Worked great!!! Paid for itself first time out...
We used this to locate a troublesome noise that only happened on engine shutdown. Turned out to be a loose PCV valve grommet that we couldn't isolate from all the other components. A couple of seconds with this audio stethoscope and the source of the sound was located and remedied. We also have an inductive type mechanic's stethoscope but that's better for physical knocking and not hissing. It pays to have both on hand if you plan to locate the source of trouble.

Ok for the money. Muffled sound
Very tight in your ears. Sound quality muffled.

Waste
No does not amplify sounds at all. Very uncomfortable fit. Not durable, and not worth the money.

Another stethoscope option for the arsenal
One of several automotive stethoscopes I own. It's nice to have this one with the rubber funnel end. The metal tube doesn't like to be bent; I may replace it with a 1/4" OD tube that bends easy.

Perfect tool for its purpose
had to find an air leak in a Chiropractic table, lead me right to it. The perfect tool for finding squeaks too.
