I have one. Just got back from a 11 day Sierra trip where it snowed, wind howled, got into the teens one night, stayed above 11,000 most nights. I never zipped the bag up, or used the hood. I will this winter, camping at home in Vt. and NY. I have zero issue with EMS products- they're my toy store and we have lots . We have 30 degree EMS down bags that are 25 years old and still going strong. My wife used hers this trip. She's going to double them for the winter. We also have synthetic -15 bags we're replacing because of bulk. If you're a cold sleeper, this bag would be an excellent choice for the money. Compressed well, lofted quickly, nice feel, no down loss. I expect to have mine for another 20 years.
