I hope I just had bad experience, but I have the aqua with backlight. About 2 years in, the display got terrible; hardly any contrast, especially in the edges. About 3 years in, the rubber buttons just crumbled away; so no more waterproof.
Can’t read anyways anymore, the contrast by now is like egg white on snow white. Didn’t mistreat, it was always stored dry and in no direct sunlight.
