Bests & Worsts Reviews from Amazon

I just got these gloves and they look nice and feel comfortable (although I haven't used them yet). I was going to get a small since my hand measures 7.5 inches, but everyone said to order a size up; I waffled and decided to go with what everyone said. I think I could have gotten away with a small, but the medium fits pretty good - a little loose, but I guess better a little loose than tight? Here is a picture of the back of the packaging to show how the sizing works. I don't think I saw this when I was ordering.
