3AQK-4PK Thermal Mylar Blankets, Pack of 4

Emergency Disaster Systems sent this item very quickly and had good customer service - polite, helpful, relatively quick to respond.This product is great for emergencies - small, light weight, great to take on outdoor activities for an emergency or to have in the car. It's very light weight (made of material like a mylar balloon), and while it can tear somewhat easily, it's made mostly for emergency use, not frequent use. It reflects body heat and can be really important for survival. Is a great addition during cold weather camping - lay over top of sleeping bag as an extra layer of insulation.As far as buying these on Amazon, keep your eyes out for frequent price changes - prices can vary by a great deal, both from seller to seller and even from week to week from the same seller, often by quite a lot. I've paid anywhere from $4 to $10 for a 4 pk., sometimes with free shipping, sometimes not.In summary, good product, can be a life saver, especially for the money, but keep an eye out for price variations and fluctuations. Emergency Disaster Systems was a great seller to buy them from.

These come individually packed in sets of four, keep one in your house, car, backpack, etc... they keep you far warmer than I ever thought and are well worth the cost.the Mylar is very fragile though, I managed to average three days use before it started to peel, this is a problem with all survival blankets so i won't hold it against this product and for the cost and weight you can carry several of these before it becomes a problem.

I buy these to keep in my go bags and a few different packs I carry morel and ginseng hunting. And I was recently ginseng hinting and got stuck a mile from where I parked my car in some pretty rough terrain. I took about ten feet of paracord and found a small tree that had fell and was leaning against a preferred. I draped then emergency blanket over the small tree and tied the four corners off to some surrounding saplings. It took around 5 mins to put together and worked beautifully as a small makeshift tent. I used to carry a 8 by 10 tarp until I discovered mylar. It's much lighter easier to carry in small packs and cheaper as well as reusable. I would recommend this to anyone from a stay at home mom to keep in her mo I van to avid outdoorsman and women. Many uses for this product sky's the limit and best of all they are cheap. I used one also in m garden this year, the birds do t like it even with very little wind it is loud and moves almost constAnt as well reflective 3 ways to deter birds from your garden. Well worth the price :)

The Quake Kare emergency blanket is a lightweight mylar material, similar to what is used to make floating birthday balloons. When I first tried mine in early autumn, I did not notice any big difference in comfort level. The crinkling sound that it makes was somewhat annoying to me. So I put it aside and did not think about it again.A few weeks later in October we had a freak snowstorm and extended power outage that lasted four-and-a-half nights. Bundled inside my sweater, down vest, down coat, hat, gloves and multiple afghans, I was shivering. I thought it could not hurt to try the emergency blanket again. To my amazement, within a few minutes I had stopped shaking and felt warmer. The mylar traps one's own body heat and keeps it under the blanket instead of letting that warmth drift away. During the next few days, I said many prayers of thanksgiving for the person who invented this! Sometimes at night I would wake up cold and shaking, thinking that my blanket must not be able to help any more... only to find that it had slipped off of me. Back in place, it provided warmth again. This was a sort of blind test that proved to me that its effectiveness was real. After several days of being cold, my core body temp had dropped a couple degrees and there were signs of mild hypothermia. Without that emergency blanket, I might not have fared as well.During our power outage we were losing heat in our dwelling at a rate of 5 degrees each night. There was a draft of colder air and smell of wood smoke coming from the closed vents of an attic fan. I framed one of my extra mylar sheets with some posterboard to make an effective thermal barrier and the following night the heat loss was reduced to 2 degrees.I highly recommend this product to keep in one's home and vehicle emergency preparedness kits (with enough extras for passengers). If some day you are unexpectedly exposed to cold weather for an extended time, this could save your life. Get some today!5/3/12 EDIT: A number of reviewers have noted that they ordered Quake Kare but received a bait-and-switch inferior brand. I've ordered two packs of these blankets in the last few months. In case it may help someone else, my personal experience is that SVM Products LLC or Big Fly Sports (Direct Product Distributions) send the true Quake Care product.p.s. for EI's:I had read that the mylar of emergency blankets is inert, not problematic for those who are chemically-sensitive. Recently I ordered another brand of emergency blanket that is said to be quieter. This might not be a concern for most people, but someone who is asthmatic or sensitive to chemicals may want to avoid that version. It has an extra colored layer that seems to make it more flexible, but there is a slight offgassing of the additional substance which could cause shortness of breath in susceptible individuals. The Quake Kare blanket did not cause that reaction.

Blankets received in timely fashion, but they were not exactly what was ordered.Instead of 3 packs of 4 blankets of the type advertised and displayed, what wasshipped was a pack of 12 blankets by a different manufacturer. Not used yet, sohard to tell if they are as good (or even better) than what was ordered. But whenI order a specific item, I expect to receive "that" item. There was not even anexplanatory e-mail or enclosed paper as to why the ordered items were substituted.Even if the substituted items are of good quality, it raises serious concerns as tothe credibility of the merchant and whether Amazon should be representing them. I haveseveral other items on order from BP through Amazon, so I will wait to see if thispractice of unannounced product substitution is a regular pattern. But buyers shouldbeware that what they order might not be what they get.
