Great tuning fork!
Neurologist approved! Was debating between this and a cheaper one, glad I went with this one. Good construction and gets the job done.

Crisp, Clear Sound with Solid Build
Solid and accurate — exactly what I needed for neurology and clinical exams. The tone is clean and consistent, and it’s lightweight but durable. Easy to sanitize and store in my coat pocket.

Good, but not perfect
Sturdy construction, lightweight since it's entirely aluminum. My critique is that once you hit it on your knee to perform a Weber's or Rinne's test you can hear the aluminum's resonance along with the 512 Hertz puretone. I mitigate this by either rubber-banding the base where the fork splits to reduce the resonance of the aluminum (somewhat tacky), or hold the fork's split with my fingers until there's only the puretone. This is only a minor nuisance most likely due to the aluminum the fork is made from and not necessarily its craftsmanship. Also, to successfully perform me Weber's or Rinne's test you must FIRMLY apply it to the respective parts of the skull which may cause discomfort to the patient in an attempt to successfully administer the test. I've seen more expensive tuning forks with some sort of Base that may be more comfortable for the client? This is only my first tuning fork so I do not know whether or not this is normal; overall I must say I am pleased with it's cost and its craftsmanship.

ADC 256 Hz
bought it for being 256, one of the most commonly used in medical practice. works perfectly, Rinne and Weber acoustic tests; both air and bone are very accurate. First time I used it on myself, perfect both ears both air conduction and bone conduction. First patient actually had a clinical finding proving its worth and that it works precisely. Accurate

It does what it does...
...albeit not very well, but I assume the majority of people are getting this for medical school classes and not for professional practice. In that case it should get '5 stars' for just being a cheap tuning fork any student can afford. In fact, I'd probably have given it 5 stars except that I have a very nice tuning fork I received from a friend, and compared to the quality, finish, and tune from the nice one, I can definitely see why this one is as inexpensive as it is. Bottom Line: If you're in med school, get it.
