Have been using fingerless gloves but these are better since I can decide when I need to expose my finger and or thumb to the cold. Not 5* because the magnets are impractical (great idea but does not work). I measured my hands and the guide suggests a size 'small' (and there should have been room to spare). Unfortunately, I had to change it for a 'medium'. Even then, the medium is a tight fit. However, I must say that the exchange was simple and easy; albeit an inconvenience.
I suffer from cold hands and these are perfect for reaching in my pocket & retrieving dog treats. Plus if I need to fine tune my camera, I no longer need to remove whole glove.
Small unisex size just fit ladies size 7 hands.
I personally do not use the magnets, but the thumb magnet position just doesn't work. Top section doesn't bend back enough to reach.
