I've been seeing sales for the OEM bands lately and obviously they are the best to get because it's the original band.. but even with the sale they're still expensive. I've seen $8 sport bands on Amazon get amazing reviews but the question is, what's the quality like? Ideally I'd want to switch bands often and have a variety of colors and with the OEM bands you can't do that cause it's so expensive so this is the best alternative for me. Just wondering if anyone's had good experiences with the cheap sport bands on amazon. Thanks!
