There I was...cold...wet...freezing...and near death... Ok, maybe not that perilous and life threatening. But, I was chilled and wet after an unexpected dip into the spring fed river from my kayak. Courtesy of a collision with a deadfall in some fast moving water. The sun was already behind the tall ridgeline and the afternoon shadows in the rivers valley were growing long. By the time I'd paddled the last couple of miles to my campsite through the now unknown river due to the spring "100 Year Flood", the chill was setting in and being encouraged by the headwind that appeared out of nowhere on this calm day. As I rounded the bend in the shadow of the ridge, I breathed a sigh of relief that there was a semblance of a campsite left in spite of the flood. After beaching the yak I started the search for some tinder and kindling to warm the bones. I wasn't hopeful for an easy fire build due to being right on the river and rainshowers the night before. Just as I was prepping the tinder bundle and cursing another gust of chilling wind, I remembered that I'd brought along a new firestarter I'd seen and wanted to test. While I'd planned to test the firestarter in different and controlled situations with a variety of sparking elements, I thought this was a pertinent and perfect situation. Replaying the memory of my backpack starting to float down the river when my kayak showed its rolling skills, I hoped that the factory packaging and the ziplock bag I'd placed the cubes in to would be enough to keep the unknown quality of firestarter dry. Pulling my pack from the Contractor grade trash bag, I saw the discoloration of the fabric from the water and my hopes began to wane. I unzipped the fire pouch on the pack and saw a few drops of water on the outside of the ziplock. I opened the baggie which appeared dry inside and grabbed the cubes from inside. Popping one from it's foil sealed blister pack, I placed it inside the tinder bundle, grabbed the lighter from the fire pouch, blew out some moisture, struck the wheel checking for a spark, and wondered if these cubes would be as difficult to light as others I've tried in the past. As soon as another gust of wind subsided, I struck the wheel of the lighter next to the cube, and like our ancestors before us found delight and relief in the birth of a warming fire. Now on to the review! I first saw these firestarters in a kayaking video where their name was mentioned, the quantity, and that you could get them in the Big Box stores in the BBQ area. I remember thinking "Weber? Weber Grills came out with a firestarter???" Knowing Weber's quality, I wanted some right then. Not for BBQ'ing, but for Survival. My trip to the store that day yielded nothing, so I ordered some that night off of Amazon. During an impromptu trip to Home Destruction the next day, I found myself walking through the BBQ section and remembered to look for them. And there they were. 24 cubes for $4 or $5. I snatched up a box of them and remembered paying a similar price for 8 or 12 of "Survival" firestarters not that long ago. When time permitted later that day, I opened the box to find a foil covered, 24 cube blister pack of firestarters. Understand that this isn't the Heavy Duty foil that you find on other packaging of similar items. This is basic foil that permits you to easily pop a cube through, in the comfort of your patio or deck, to get a fire going to grill some goodness. Taking that in to consideration when I put 6 of the cubes in my backpack, I carefully cut 6 of the cubes from the 24pk sheet, being mindful of the foil covering of not only the 6 I was taking, but the remainder on the sheet. My concern being puncturing the foil and the individual cube "drying out" and rendering it useless. As previously stated, I then placed them in to a Ziploc for waterproofing. Pro's- COST- For the quantity you're getting, it's a no brainer compared to "Survival" packaged firestarters. QUALITY/RELIABILITY- The cube lit as soon as a spark hit it. While this may be age and airtight seal dependent, it worked in a difficult situation. BURN TIME- I didn't put a clock to the burn time of the cube. But I did take note that it burned for a couple of minutes, and was enough to get tinder and kindling to burn in a humid environment. Con's- PACKAGING- These aren't packaged for "Survival." They're packaged to get a grill going on your patio. HOWEVER, as my situation showed, with just the minimum in planning ahead for the cubes, they'll perform as expected. AGE/LONGEVITY- I don't know what mfg specs are for the expected lifespan of these are, but I've no doubt that if they're stored in an Airtight/Waterproof container, then they'll exceed your expectations. DURABILITY- Only time will tell. I'm going to throw some in all of my packs to see how they endure the bumps and jostling. SO, give these a shot and see how they do in your situation or planning. We may have found an inexpensive and quality alternative for "Survival" firestarters, IF repackaged for such. I know they worked for me for building 4 fires in 2 days in a humid environment. ENJOY!
