This is perfect for people who struggle to keep warm during the cold 100"x90", you can easily make yourself into a "taco" one side for the back one side for the front, and its plenty hot for even on medium.. It is somewhat in a way can save you money on heating if you know that you won't be moving a lot.. I think it is 200w's on both on high (100w each) is much better than a space heater from anywhere from 500w to 1500w... This also means if you have a "Solar Power Bank" if in a total power outage having something like a 500wh and above you can have a night worth of heat on medium..
The only problem i have is how the "cords behave" but i think its simply due to how i use it.
