Car Mechanic Stethoscope, Automotive Stethoscope Engine Diagnostic Tool, Automotive Tools Universal for Car Truck SUV Motorcycle RV

This Mechanic Stethoscope works really good you can hear everything in the engine while it's running, it is that sensitive so when listening to your engine you got to make sure to keep it from touching anything that is not supposed to or knocking around in order to hear the sound of the engine correctly but overall this is a good product. I would also recommend this if you're looking to buy a new car you can listen to the engine as you're going over the new car like I'm doing to do.

This product is basically a must-have for any shade tree mechanic diagnosing noises under the hood. I had a horrible whining sound on my truck, and tried to use the old screwdriver-up-to-the-ear trick to diagnose the source of noise. That method did not give me quite nearly the definitive proof that this stethoscope provided.Once I used this product, I was easily able to trace the source of the noise back to my trucks A/C Compressor. The extra long probe made it very easy to get down low in the engine bay and make solid contact with the compressor. Found the noise!The earpieces fit nicely in my ears, providing good comfort and function during use, and the whole tool feels to be of high build quality. It should last indefinitely with proper storage during non use.As a bonus, you get to feel like a "car doctor", pulling out your handy dandy auto stethoscope. Worth it for that novelty alone!

This stethoscope works fairly well. I was able to pinpoint a ticking noise in the engine, which made it worth the purchase. The tubing is a two-piece design that screws together, and it feels a little flimsy because of that. However, it does what it's meant to do and is affordable enough to keep in the toolbox for quick diagnostics.

I use this to set the "beat" of the clocks I work on. Works great and very easy to use. They don't clamp your head and are very comfortable. This stethoscope picks up even the slightest bit of mechanical noise.

The mechanic's stethoscope works quite well. I purchased it to isolate valve chattering noise, and it certainly amplified and highlighted the fact that I need to adjust the valve lash. It's a good—quality product and well-constructed.

Can't go wrong, it's a cheap stethoscope with an extension. Be careful for your hearing as some vibrations can really resonate and are very loud in the stethoscope. Recommend touching the probe sideways to the vibrating component instead of just pushing it straight on. Overall 10/10 for the price. Helped me diagnose a failed bearing on a serpentine system and saved me an hour of work disassembling the whole thing instead of just the part that needed replaced.

For the price, these two mechanical stethoscopes worked better than expected. Why two? For the price I didn't figure that either one would last very long. But as a DIY'er I don't believe that I will ever need but one. It helped me pin point a noise bearing in a tight spot on my Toyota Highlander. Saved me valuable time, effort, and money replacing the wrong things until I got it right. I will be gifting the other one to my son.

Works well! Great tool to find those ticks and taps on a motor
