Don't waste your money! - UST Delta Stormproof Lighter

Bought the UST Delta Stormproof Lighter for backpacking and hunting a couple years ago. Seemed to work fine before a trek, but was inconsistant in lighting and frustrating to use. Broke it out recently for another trek and it simple would not light! Of course I bought supposedly the best butane (NEON quintuple refined premium butane) so have to discount that as a problem. It seems to have good spark so what else? After ensuring it was full of butane and tried again for the umpteenth time, the gas wouldn't stop for about five minutes.
GET YOURSELF AN OLD FASHIONED ZIPPO AND BE SURE TO HAVE A RELIABLE LIGHTER!!
