Helpful diagnostic tool
This worked better than I hoped. I used it to track down two ticking lifters on a 400 SBC. Listening to each one with the probe, I could easily hear the difference. I wear hearing aides, and the headset gave me no problems at all.

Can You Hear Me Now..!
At the $50 dollar price point, it works exceptional well... Start with the volume at the lowest setting to establish a baseline, and then increase volume. 9V (not included) The final results on my 01 Tundra 3.4 SR5 making the infamous whining noise was actually the Power Steering Pump itself. I also discovered with the use of this device that #5 cylinder was misfireing.... (Tick, Tick, Tick) Mechanic Joke.. Take Care...

I like it.
the listening device is good. 2 sizes for probes. headphones suck. I don't use them. I use a pair of noise canceling headphones and just plug into those. help isolate the noise more. I'd say they are more helpful I'm picking out certain noises over standard stethoscopes.

Great
Used to find a ticking lifter on a v8 Pontiac. Works great.

It might be good for detecting higher pitched noises, but not for detecting lower pitched noises
As an electrical maintenance technician, I have Dozens of motors to do preventive maintenance on. I must listen to each motor in three different places to assess bearings. This item does not work as well as a regular manual automotive stethoscope. It's lowest range of hearing is one hundred Hertz, and much of the noise I am listening for is below that level. It would probably be better if you need to listen to Higher pitched Noises.

It's ok for the money.
It works pretty well for the cost. Other than that, not much else to say other than it beats using a screw driver to listen.

I have hearing aids. So I needed something to go over my hearing aids ( head phones ).

Received item today. Fast delivery but one small item missing. The battery which make the item work. Package should have been checked before shipment. Another note is that this package was unsealed which made it easy for someone to remove the battery. For that I will only give a 3 star.
