I've only used these on a couple of mid 40's rides so far, but I'm enjoying them. I have really warm hands by nature, so I don't even need full finger gloves until 50 or below. So, at 45 my hands stayed quite toasty (almost too warm). My hands did end up just a little bit sweaty at the end of my 30 minute commute, but not too bad. I think the hand sweating thing is just my issue, so I still gave it 5 stars.
