These are some pretty good sheets that I do not have many complaints about. I washed them prior to using as I always do with sheets and they are relatively soft to sleep on. I am not so sure about the "smart temperature" feature as I did not notice much difference compared to the sheets I was using previously. I live in Florida so I was hoping that the sheets would keep me cool but I have not noticed much difference so far. I have the light grey color and I think they look pretty nice and neutral. Overall, I am happy but I do not notice anything special with the sheets.
