Well it has not been cold enough to really use this but to me they are a little clumsy and bulky. You can't use fingerless gloves with the thumb cover on and taking off the thumb cover is a little difficult and you probably need to leave it off so it may defeat the purpose. I think it's more convenient just to have shorty acrylic fingerless gloves and then a regular glove over that. Maybe if it gets cold, I will change my mind but for now I don't use it.
