I had been looking at this spirit burner for months and had it in my cart ready to purchase then back out again and on the fence about buying it not because of its price or reviews but for the simple reason it's really really easy to manufacture a penny-stove and I always intend to build one but never have. I finally ordered this stove last week on Monday. I am a Prime member and was supposed to have gotten it by Thursday, but, well things happen. For whatever reason, it ended up being late and was supposed to ship Friday by 9 PM. Next thing I know it's arriving Monday by 9 PM instead and I did get notification from Amazon that my purchase was arriving late and they were very apologetic. My Redcamp spirit burner did arrive yesterday and was here when I got home from work. I took it out this morning and did a three-part YouTube unboxing and review for my channel. I was very impressed with the quality. It is much heavier duty than I expected. I thought the brass would be thinner but this is quite thick and seems like it will be very durable over the long run. I used denatured alcohol as my choice of stove fule and with the optimal wind conditions today and even without a wind screed I had breakfast in six minutes from start to end. I did not do a timed boil test as I find them a complete waste of time. Boil time will vary depending on a host of reasons and factors that have nothing to do with the quality of the product and are all due to environmental variables and/or fuel choice. Of course, they boil water. If you are in some kind of hurry to eat you should have items you can just open and eat without cooking, to begin with. I will continue to use this as my main method for cooking while I am away at camp as I am generally very busy when I'm out and prefer quick-cook or instant type foods. You can cook on this burner as long as you need and can cook foods that take much longer to cook, however, I try and keep my cooking times on a spirit burner to fifteen minutes or less when I can to conserve fuel. I did do a leak test after my second burn to see if any alcohol leaked out of the cap with the seal in it and mine does not leak. I even turned the burner over on its side as if it had been knocked over and left it that way for several hours and there was no sign at all that even a drop of alcohol was lost. If you are having problems with leakage you are probably cross-threading your lid and the seal is not making good contact. Secondly, always make sure you are storing your burner with the extra fule upright so that you do not have to worry about leaks in the first place. An ounce of prevention is worth a pound of cure! I suggest using Everclear as your stove fuel if you would like it to be multi-purpose as it can also be used to make medicine, for recreational drinking, as cooking fuel, and as an antiseptic. In the photo I provided, and I know you cannot tell by the image, the stove is lit and burning. Part of the inerrant danger in alcohol stoves is frequently people striking their stove with a lighter or match and thining it did not ignite then going back in for a second attempt and getting severely burned. When the stove is first lit you cannot see the flame unless it's dark so be very cautious and place your hand high up over the top of the burner to check for heat BEFORE you stick your fingers or hands close for a second attempt at lighting! Very happy with my purchase and I look forward to a TON of use because this was purchased to be my main cook system for out at my basecamp. Judging by the results of my first use it will serve me very well for a long time. Thank you Redcamp for supplying a very good and quality product.
