These worked well for my project and the quality was nice. The size was perfect and I will be ordering more.

Since I noticed that the EMF (Electromagnetic Field) output around my circuit breaker box is off the charts, I have been looking for a solution to protect myself. After reading online that Mylar is excellent for blocking EMF, I decided to go for these blankets and use one to hang in front of my CB box. It looks like a small golden curtain :-). Most importantly though it greatly reduced the EMF being directed into my kitchen. I would highly recommend this for people who have that CB box in their bedrooms - you wouldn't believe how many people have those in their bedrooms. I also keep one of the blankets in my car for possible emergencies. Great quality for a great price!

Very thin plastic, but that's probably about typical for this type of product. If using for a project involving nails or staples, they're subject to easy ripping. What really seems lower grade vs my older Korean-made Mylar sheets is the thickness of the reflective material (although with the old ones it comes off easier). Reflections aren't as clear and I can see more light through the film. That suggests that they don't reflect 'quite' as much infrared/radiant heat either.Of course, in many applications one also needs "dead air" insulation like a coat or fleece to reduce convective and/or conductive heat loss. These mylar "blankets" mostly help with the radiative part of the equation. For that they'll do. I'm not likely to use them in sub-zero conditions. Just not sure I would have paid more than a dollar a piece for them.

I like these, because you can use them for different purposes.I keep a couple of them in the truck...in case of emergency. Not only my emergency, but if I see an accident, or a homeless person thar could use one, they are inexpensive enough to give away. I also covered my south facing bedroom window with one to keep the sun out, and keep it cooler. I also have seeds and tomato plants growing in my bathroom window, and I use these to reflect the sun onto the plants. They really do have so many purposes!

These things are really great; they truly do keep in warmth. Very cool that it's waterproof also. A great gift for ppl on the street, costs me a buck or two but can make a big difference in someones life.

I bought this because not all my first aid kits have an emergency blankets so I thought to add it to those without.

Emergency preparedness has been on my mind. I added these to both of our car glove boxes, to our camping and hiking gear and our beach gear. Hopefully we won't ever need to use one. 6 pack is great.

I hang them in my south facing windows on hot sunny days. You can see through them enough to know what's going on outside. They actually are kind of cool looking with the rectangular folds throughout. Excellent job of keeping my upstairs south-facing room 20 degrees cooler than before I put them up. We don't have air conditioners up here in Maine. This is so much more efficient.
