Not quite the right frequency
The product is nice and comes in nice packaging but after measuring the frequency on an audio analyzer I found it resonates at 517 hz

Never once hit 528hz
This product doesn't accomplish the only job it is manufactured to do.... Produce a 528hz frequency. I have a confirmed calibrated and very accurate decibal reader. This produces 549hz-554hz depending on how hard you blow. Either way, it produces NO LESS than 549hz no matter what you do. I was suspicious given the price and my suspicions were instantly made reality.
