Easy to set up and use, but true test will come this winter. Heat levels range from 1 to 10 but it never got hot like a heating pad - I think this is to be used more to gently warm a bed in an otherwise cool-ish room. It also has a timer - very handy, since you might want to use it just to fall asleep and not all night long. Pockets are deep to accommodate thick mattress. Little bulky in lower corner where remotes plug into heating element - probably wouldn't disturb sleeper but you can see it's there. Looong cords to reach outlet even if it's not close to bed.
