Dr.Dabber customer service is the best I have ever experienced. They are fast to respond, and really care about their customers. Any slight issues I have had with my unit have been resolved within hours. I am able to rely on my vape knowing I have an awesome team behind me! They went above and beyond to make sure everything was running smoothly, and even followed up. I can't say enough about how helpful they have been with me, I have recommended this company to friends and haven't regretted it! The Dr. Dabber family is the best and it's extremely reassuring to know that I have a reliable vape, reliable backing, and really well spirited folks running the customer service department! Viva Dr. Dabber!
