Hello, and thank you for your comment. We apologize to hear about your issues with your LTR200. Once the butane is low, igniting your lighter will become increasingly difficult, just like most items that require fuel. We also advise using Bernzomatic brand butane to refill your lighter, as the quality is much higher and will function easier as well. So we can better assist you and learn more about your experience, please email us at Bernzomatic@WorthingtonIndustries.com. Thank you.
