I can attest to the power of the slanket. I purchased this for my wife, she has not gone a night without using it. She loves it since she can cuddle up and still do work, grade papers, eat ice cream or play Wii. The sleeves and length are just long enough so that nothing is exposed. If you have someone in your life that is always cold, buy this! Stay away from the infomercial "snuggie" it is of a lesser quality!
