Used it for a while but started to feel like it wasn't working for me and my partner. So switched back to a standard duvet. It does the job perfectly and did help to keep my partner cool and kept me somewhat warm. Still going to use this in the guest bedroom for them to decide on how warm or cold they want to be.. Kieron.
