Just wondering if anyone has ever used one of these Volcano Stove Swiss Ranger Kit?  My wife bought one for me for Christmas from 
 https://www.cheaperthandirt.com/WX130-509-534.html and we just tried it out and it worked great.  It took about 5 minutes to boil water.  I was not surte if that was fast or not but it seemed that way to me especially for something that only cost $4.00.  Well just wondering if anyone has experience using these things. 
Resurrecting an old thread here, but has anyone ever used one of these volcano stoves and a Kelly Kettle type stove (the Kelly Kettle is also called a Ghillie stove, a Thermette, and a Bengahzi Boiler).  If so, I'm wondering how the two compare.
