“I was hoping the Pulsar DL 4. 0 would be the perfect pocket carry and unfortunately I've been pretty disappointed with it. The seal between the battery and the casing is not terribly secure and I've experienced multiple occasions where live resin 510 carts have leaked badly coating the entire chassis and contact points. Can't really recommend this one in good faith. Went with a different model and brand from LighterUSA after a few weeks with this one.”
