I finally gave into the year-long temptation to get an old Sony eReader (the PRS-300 to be exact). I got it for 10€, with a broken battery. There were some books on it as well. It's very similar in size to older 6 inch reader, a little less wide. Excited to read my first book on it after changing the battery. Thanks to @ifixcoinops for the inspiration
I love when custom Firmware from 2011 is still available, just works and really easy to install 
I noticed something weird with the PRS 300. The letters start fading after a few page turns, as if the ink is running low. It's really distracting. Can this be fixed/changed? #prs300 #ereader #eink
@becca @jollysea is this to do with the the refresh rate? I think on my e book you can save battery by not refreshing every page. It's in the settings.

@Tattooed_Mummy I suspect that, but couldn't find any related setting. I'll look again later, maybe its under power / battery settings.

Edit: couldn't find anything
