Knowing when to replace your pen comes down to recognizing the signs. Early issues are often fixable. Mid-life wear is normal. End-of-life signals mean it's time to move on. When in doubt, replace—especially if it's a safety concern. And always dispose of old devices properly.

Remember, this is just about the hardware. The CBD cartridge is your separate choice. You're in control. Choose a pen that fits your lifestyle, and don't be afraid to upgrade when it's time.
