I'd never had an electric blanket before, I was suprised by how nice the heat feels!
When I turn it on the heat isn't steady on at the number i selected. It seems to pulse on and off. On 3 and belove its not as noticable but on setting 4 and above it seems to pulse on at close to full power for a few seconds then turn off. It gets so warm that it will pull me mostely out of sleep for a second then it shuts off and I will drift off till I get too cold and not fully wake me up but I am aware that I'm cold.
On the lower settings it doesn't seem to be so drastic that it's an issue.
If you have colder* space I would not recommend this product as it is not working for me.
*note that I live in southern California.
It's not cold here compared to LOTS of other places.
