Generally, Alesis mesh heads have a lifespan of between 5 and 10 years, depending on your usage. Regular maintenance and care of your eDrums will help ensure they last for the maximum amount of time. The bass drum pad is usually the first to wear out.
It is important to check your mesh heads regularly for signs of wear and tear, and replace them when necessary. You should also clean your eDrums regularly to prevent dirt and dust from building up.
