I have 2 lighters by Vector KGM, a single and dual torch. I bought the single a year ago, and dual about 6 months ago. They have never failed me once, the single runs out of fuel fast, but is good enough to heat a few caps. It takes more than 10 seconds to click, but the single flame is precise and easy to focus the heat where I want.
The 2 flame torch last forever, if I turn the flame up and i can heat about 90 percent of the cap with it and it clicks in about 5 seconds. I don't usually have the flame set very high as it heats in under ten seconds and the flame layout allows you to focus it fairly well. This one last forever and I can go a few days without refilling it, although I refill them if I'm going out.
I usually have them both with me and I have the single in a case with my Vapcap and some herb for the on the go, and the single is only used as backup when i'm on the go. The dual finds a place in my pocket or in my backpack. I have not been caring with these lighters, they have been beat up from drops and riding around in loose pockets with keys and all kinds of stuff as you can see from the pics. But they work, they are solid metal from what I can tell.
After looking online and seeing the billions of options out there, I decided to go to some smoke shops, there are so many around me, and i like going there anyways, they always have cool shit there. I bought some cheap lighters at first for around 5-15 dollars, they all failed on me after a month or worked intermittently. I decided to spend a bit more and found the Vector Single Flame Torch for 20 dollars, it had a nice case and packaging, but I thought who knows, it could fail, but it never did and I went back 6 months later and bought the duel flame torch for 30 dollars.
That's my 2 cents of what to get if your on the fence. Also I have not tested there warranty service, but they have a No Proof Warranty, you basically pay shipping send the lighter off and they will send it back fixed, no proof of purchase required.
