Bought this Heated blanket after a Sunbeam gave out after only a few years. This one is very soft, and it's true that you can hardly detect the wires. The king has dual controls, which my husband and I both love.
I was apprehensive about the level of heat it would put out after reading many reviews all over the internet about how modern electric blankets (now called "heating blankets") don;t put out as much heat as their vintage counterparts.
No need to worry about that. I used to keep the Sunbeam on high, even when it was young and working "properly". This SoftHeat only needs to be on low (3 or 4) to keep me plenty toasty, and that's saying a lot. I am perpetually cold.
The size is plenty generous, unlike some electric blankets that barely seem to make it over the edges of the bed. I never feel like I'm tugging at it to cover me up to my neck. It's lightweight, but yet warmer than a lot of other blankets even when turned off. Amazing.
I didn't give it five stars because of the cord. I've had other dual-control King blankets, and they all only had one plug total. This one has two plugs--one for each controller. I'll spare you the logistics of the underneath of my bed vs. the electrical outlet, but let me say that because of the addl. plug, we actually had to move our massively heavy king bed over several inches in order to accommodate the extra plug. The bed rested in its previous spot for over ten years, so now the divots where it used to rest are apparent. Not earth-shaking, but annoying that this wasn't designed to end up with only one plug into the wall. Oh well.
Happy with it overall. We've only had it since October 2010 (it's now Jan 2011), so I can't comment on its longevity yet, but so far, so good. I hope it lasts a long time, because I like it as much or more than any electric blanket I've had in my life (and I've used them steadily since I was a child).
