For the money, these are a five star.  I have no complaints.  The saving grace for me is that I can wear a lightweight pair of gloves or fingerless gloves inside the mittens, which gets me into the single digits F comfortably.  Without those, they would not have been adequate for me for those temps.  Not saying they would not for others, but not for me.  Quality build, quality materials.  I don't think they'll last for decades, but for what I paid, again, no complaint.
