Sometimes the problem is more than a simple fix. Here's what to look for:

• For disposables: If the device is producing no vapor but the light blinks, it's likely empty or the battery is drained. There's no user-serviceable part inside. Trying to take it apart or charge it is a safety risk.
• For rechargeables: A burnt taste after charging often means the coil is old or the e-liquid is low. Try a fresh coil or top up the tank. If the device doesn't fire at all, check the connections—clean the contacts with a dry cloth.
• Check the e-liquid level: Low liquid can cause a burnt taste and poor vapor. Refill or replace the pod.
