Worked to zero degrees
Just used it on a winter boy scout trip in granby Colorado. Minus 2 degrees. It kept me very comfortable. I was wearing 4 layers up top and two on my legs, but the good thing was I had plenty of room and never felt constricted. I am 6'1" and 220. This bag is plenty big. Too heavy and bulky for anything but car camping or short backpacking trips. But for $80 it is really impressive deal.

Definitely not for backpacking...
This is a quality, super warm bag at a great price, but there's no way you'd want to try and haul it on foot. For car/truck/canoe/etc. camping in cold weather it is a great deal, but there are much better options out there for backpacking.
