Electric blanket and throws - help

[bingohandjob]

Talk to me about electric blankets and throws. Any good ones? We've got king size Tempur mattress so has to be overblanket and I'm tempted by the Relaxwell heated throws for the sofas but any clue if they're any good/worth the £££? Thanks!

I've used over and under blankets for years.

I've never noticed the difference between the cheap brands and the expensive ones except the cheaper ones usually have controls marked 1-3 and expensive ones 1-10.

It's one of those items I think where it isn't worth buying the expensive version.
