I bought a Tolino Vision 6 about two years ago (because it was in super sale). I really liked it! Battery life isn't great, but it warns you way ahead of time so you can put it on charge. If I recall correctly I could read a couple of books, around 400 pages each before getting the warning. I almost always read with the reader's light on.
I did miss the "automatic" sorting into series my Libra 2 has when transferring from Calibre, but to me that wouldn't be dealbreaker.
I gave the Tolino to my daughter a year ago, and she's happy with it. She doesn't keep comparing it to the Libra 2.
