My reply was a huge HELL NO!!!
I have now eaten my words,
Temp around my home have been around -11 at night, and we were sleeping with three blankets and a goose down duvet, which is really heavy, and a mission to turn under.
Hubby brought home this super-blanket a few days ago, as an early Eid present for me. 
After one night, all those other blankets have been packed away, and my bed now only has this wonderful soft blanket made by Mashudu. A proudly South African company!
It has this really soft, off white sheep fleece on the under side, and the top has a fluffy, block design, available in an array of colours. They also give you two pillow cases in the same warm soft material so my head is also super warm when we use this,(never saw another blanket that comes with pillow cases)
I love that I don't have all the weight on top of me, and that this single blanket keeps us totally toasty through out the night!! When I sleep in under my new favourite blanky, I can feel the warmth almost radiating and being kept close to my body, it's like sleeping in a warm cloud!
This is the softest blanket I have ever felt and it makes getting out of bed in the morning close to impossible,
