Hello friends, yes i did use one, and i still have two. The Hexi-stove is just a new name of the old Esbit-stove, the way i see it, the stove was so good, that stanport camping goods co. made some. And now this new hexi-stove brand is out. I have one Esbit-stove and one off brand. If any of you try boiling water with it, the best way is to just use some US Army compressed trioxane fuel bars, around the same cost as hexamine. But thay are hotter, and i know boil water before the bar is used up, i did not time it, but i know it works. Most of the bars are just short enough to fit the stove, some times i snap one in two, and lay the two in the stove, and light. And one of you was talking about using an aluminum foil windscreen, great idea. most of the time i used rocks, like a wall around my stove. But thank you for your idea of the foil, i always keep some in my survival kit. By the way, the fuel bars from Esbit and the Trioxane stoves, still can be used, with out the stoves. You can do like me, and make one out of rocks, bricks, large wood parts, or i have used a small hole in the dirt. I don't know it all, but i do know this stove. your friend at the post, Donald S.
