Review on Black & Silver Refillable Butane Torch Lighter Set - 2pcs, with 360° Flexible Neck, Flashlight, for Grill BBQ Camping - Ideal Mens Gifts (Butane Gas Not Included) by Paul Ziegler

I've had the lighters for a week now. Initially, they fill up easily and light up quickly. But after a while, no matter how intense we have it, the flame gets deeper and dimmer and dimmer. For 5-6 uses these things don't produce a flame. I hear gas inside. i know it's full I hear the sparks go out. There's just no fire. At least a few hours. Then they randomly work, though not as well as initially and not for as long, but more like "well, that's better than nothing". Same story with both lighters. which (IMO) negates the benefits of the extended tip (keep your hands off the fire).
