Great item for a cold night.  Unfortunately I got this after Oklahoma winter was over ...or so we thought.  First part of April temp dropped again and I rushed home from work to put on my bed. .it went on easy enough but did create a small issue trying to cover with fitted sheet.  I would definitely make sure to do corners that are hard to get get done first.  But it was well worth the additional struggle once I got in bed and sheets were warm.  It has dual controls so I could adjust my husbands side to. off and mine was high.  I jokingly told my husband if he could feel the warmth he was on my side of the bed!.  I am definitely ready for winter. Great item.
