Bests & Worsts Reviews from Amazon

I have the previous generation oasis as well (on the left side in the pics) and wanted this one for reading at night. Overall there's not many differences between the two, so if the light tone customizability isn't important to you I wouldn't particularly recommend this one over the 9th gen. However, the lighting is noticeably more even with the 10th gen (my older one visibly fades from one side to the other) and there's a ton of variability in the tone of the screen. Overall, for me it was worth it, but your mileage may vary if you don't read in a dark room (so as not to wake the spouse) before bed very often.
