Will keep because of the comfort level. It?s sturdy and very stylish. I wont be knocking on anyones doors to praise them tho. Anyways, hope this helps someone and any further questions feel free to ask. If you want a gaming mouse for productivity, my pick would be the G502, but it does have a terrible cable unless you get the very expensive wireless version. I use these for kayaking mainly, they are lightweight and work real good around water. Pick the workout option for you and hit the iron. Bought these as a gift for my husband who loves his Keen hiking boots so much that he bought a back-up pair of Keen boots. I got an 8 1/2 in slipper as didnt want it snug. Id say that gives you about 9-10 days of battery life, which is excellent, in my book.
