Sometimes, despite your best efforts, a vape just doesn't recover. If you notice any of these, it's time to replace it:

• Persistent leaking after you've stored it upright. The seals may be compromised.
• A metallic or burnt taste that won't go away. The coil is likely damaged from heat.
• The device feels unusually hot even after cooling. That could signal a battery issue.

Don't try to fix these yourself—disposables aren't meant to be repaired. Just recycle it properly and grab a fresh one.
