Used them for many years. Now I use mostly dual and triple flame lighters, so they aren't in regular rotation. However, since their price makes them 'disposable', I usually take one in my carry-on when I fly. I've got a little better than 50% rate getting them through security. I've still got a lot of them around the house - I'd grabbed a dozen or more when it looked like Wallyworld was dropping them a few years ago. And, I got a dozen of the old softer flame model for under $20 from a disreputable daily deal site a while back. I like those because I've been able to convince more than a couple TSA agents that they weren't really a torch and it'd be OK to let me hang onto them.
