Has anyone tried the AMK SOL Survival Blankets? I'm curious about how they compare to Heat Sheets and Mylar blankets in real life. I've seen them in an Equipped to Endure video once or twice and found them in a local outdoor store today. For $3.99 for a single and $5.49 for a double, they were just the right price for Santa's elf to pick up one of each for my son and I. They don't weigh much more than a Mylar blanket and less than a Heat Sheet. I liked the manufacturer's description so thought we'd try them out:

The most advanced emergency blanket on the market - meticulously designed never to fail when you're counting on it with your life. It all starts with the material -vacuum-metalized polyethylene reflects 90% of your body heat while also offering a number of other important features that set it apart from traditional mylar blankets: it opens easily and will not shred if nicked or punctured, rips and tears can be repaired, it is quiet and won't crinkle in high winds, and its high-visibility orange exterior makes it easy for rescuers to find you. Plus, survival tips and techniques are printed directly on the blanket so you have them when you need them. Sized to fit two people.
