Haven't needed to plug in yet, just use as a throw over me when in reclining chair. Haven't had to wash yet either, so 4 star pending further experience with it.
Since the above it has had two LG washer/dryer experiences & none the worse for it. It gets thrown on the floor, then picked up to keep me warm in my reclining chair several times a day. I only needed the electric blanket capability twice & it worked just fine.
Though I'm a demanding user & don't spare it, day by day, it survives intact. I would thoroughly recommend it. Visitors admire the colour and soft plush finish.
