Hey Jim,Thanx for the comparison info on these stoves,I have an Esbit winger,2-Stansport,& 4-No name German army stoves,they are Exactly the same as,one another.The stansports come with the pill type fuel,the german ones come with the wafer type.I was toying around with them awhile back,& found that candle wax dripped upon a burning fuel tab(pill type)will flame up fairly quick like & burn with gusto/ferocity!I didn't make the means of boiling water,but I'm thinking I'll do it again for a cup of water with candle,& without, to see if there is a Big difference.It stinks something horrible though,& smokes as bad,probably wouldn't be good in shelter situ.Happy Thanksgiving,almost!
