## Questions & Answers

**Q: What kind of lighter or “fuel cell” it needed for the lighter to work?**
A: I can go buy the cheap lighters take the assembly off of and they work like a champ inside there

**Q: Will it work with a BIC lighter, or only generic lighters?**
A: No - Will only work with their supplied Refillable lighter. Mine leaked all the fuel out within 15 minutes of filling it. I am hoping for a replacement from them otherwise I'm Hosed. OH & had to reorder because the first one got lost in shipment. Not really happy.

**Q: Will it get hot enough to sweat copper?**
A: Obviously it depends on the mass of the copper.  You are not going to do plumbing with it, but wired connections like a guitar jack, yes.

*by D***R on April 4, 2014*

I originally ordered one of these, along with a brick of 50 admittedly cheap lighters (super inexpensive), hoping it would work satisfactorily with them. Good news and bad news: The good news is that the refillable cartridge (which had the flint/steel removed) worked perfectly. Bad news is that it was very difficult to get it to work at all with the el-cheapo lighters I had bought with it. It may be possible to "shim" the generic lighter so as to make it more reliable, but that, and the child safety feature, make this a total pain. I also tried a 7-11 lighter, with the correct form factor, and that did not work well either. I actually pulled off the flint/steel wheel thinking that would make a difference but it did not. SO...... I found the SOTO Pocket Torch, which costs more, has no refillable insert, but doesn't have a child safety feature, and it works PERFECTLY with the cheap lighters, without any modification or special adjustment. I'll be giving them a review next! This one was a big disappointment. Get the SOTO instead.
