I found some information in the Legator's FAQ at http://www.szilagyi-jewsharp.com/news3.html Frequently Asked Questions Q: What is the estimated average lifetime of a Szilagyi jew's harp? A: Basically it depends on your playing technique. - With a normal technique (normal means not rough) your Szilagyi jew's harp can last just as many as 20 - 25 years. Although having an extremely rough technique can ruin the harp in some minutes time. - The lifetime of the jew's harp can be optimized by plucking the spring inwards. Check out the On-line Jew's harp school for more information. At an average temperature of 20° Celsius the spring can resonate approximately 31 Million times at 15° of average bending angle. - In the last 30 years there were only few complaint about having one of my costumer's Jew's harp broken less than a half year usage time.
