“Boulder Rock Vape Pods holds a good amount of vape juice, easy to refill, salt nic vape juice is recommended for this device. The key to getting more life out of the pods rather than blasting through them as much is to make sure it doesn't get too low on liquid or the coils burn up faster. I absolutely love my boulder rock. I quit smoking over 6 months now and haven't touched a cigarette since nor have I had any desire to. I highly recommend the Boulder Rock.”
