Got one for Christmas, apparently it's a nice one, with a lifetime warranty, and unlike those old ones that would break or weren't machine washable. Well damn did I sleep like a baby last night. I don't know why I never thought of this before..
wrapping yourself in electromagnetic waves cant be to good for you.. And Im usually on the electricity's side..
I live in the woods and sleep with a hot brick, if its that cold I need to warm the bed. if all else fails, theres a dog..
I knew a homeless guy in Dutch Harbor AK that would stick he coleman stove under his bunk on low when he went to sleep. Me I'd get too hot, I love the cool feeling of the sheet when I get in bed at night.
I do also, but found that if the pillows are to cold I wake with a stiff neck.. I use the brick to heat a little bit of the bed.. and then push it off to the side when I get in...
I miss such blankets... I used to have two, but it's been some time now since they broke... I couldn't find any to replace them in the meantime.
