(Part 2) Top products from r/ereader

The eye strain improvements of e-ink are due to the fact that the screen isn't "flickering" or "refreshing" itself 60 times per second like LCD screens. You're right to believe they are "easier on the eyes" (whether you need glasses or not).

Your requirements pretty much embrace every ereader out there (as opposed to LCD tablets). All the e-ink screens are pretty much dedicated readers.

• Kindles,
  
  
• Kobos,
  
  
• Nooks, or
  
  
• Onyx Booxes.
  
  All fit your bill. 6" is the most common size (there are bigger, but you pay disproportionately more).
  
  The only thing that narrows your field even somewhat is the ePub library. Kindles can read ePubs if you're willing to jump through some hoops (either by "jaibreaking" the unit or by converting files on your PC and then sending them to your unit) but they don't support them "out of the box".
  
  The "special features" aren't all fluff. Waterproof is nice if you use it by the pool (e-ink is especially suited for viewing outdoors), and some of the Kobos have native Overdrive support for checking books out of your local library for free.
  
  Finally, there are older "Pearl" screens and newer "Carta" displays when it comes to e-ink. The Carta and Carta2 screens are usually denoted as "HD" or list a dot pitch of more than 200 ppi.
  
  Screen resolution improvements in the Carta displays are a little "fluffy", but the newer models don't "ghost" after a page turn and "refresh" a little faster. But if you "settle" for a (cheaper) Pearl display, it's not the end of the world.
  
  Personally, I'd suggest the Onyx Boox C67ML Carta2, but you could get the cheapest Kindle if you can live without a frontlight and can put up with ads on the lockscreen. Both would "fill the bill".

I'm sorry, I wasn't very clear in my question but I would like to have an e-ink one, I already have an Android tablet but I'd like something which is better for the eyes (I saw that some e-ink readers also have integrated blue-light filters, that would be a nice feature) and lasts longer battery-wise. Do you know about something which could fit my needs?

I saw this for example which says it has Android and Google Play support, does someone kow if Crunchyroll manga will work with it? And is it a decent reader?

I don't always hold an ereader when I read. One thing that has come in handy is a lap desk. It comes with a slot, which may be for sticking tablets into. Here's a lapdesk I found on Amazon with the same design. I stick my Likebook Mars into it and read hands free except for turning the page. The Likebook Mars has warm lighting, which is what you're looking for.

The only Kindle with warm lighting is the Oasis 3, which is not out just yet. The Oasis is designed to be held with one hand. It has a lopsided design that puts most of the weight on one side.

Assuming European prices are equivalent to American prices, either one of these puts you a bit over budget. Cheaper options include Nooks and Kobos. These have had warm lighting for a while now, though Kindles are otherwise nicer.

You might not be looking for a e-reader so much as you are looking for a tablet with stylus input. The big difference between a tablet and an e-reader is that the e-reader is designed specifically for reading content, whereas a tablet can perform a large number of computing tasks, ranging from gaming to internet surfing/email.

For your purposes, I'd recommend a Samsung Tab S2 10" tablet:

The apps you'd use are like EZPDF and a clipboard manager like Native Clipboard or clipstack.

Backlighting is common enough among e-readers at this point, but adding an SD card slot narrows the field a lot. You're basically looking at something like an Inkbook Lumos (I'm not sure if that's a per se upgrade from the Kobo) at the low end and the Boyue Likebook Mars or so on in the midrange.

That said, alternately, at that point you'd also have the Kindle Paperwhite 32GB as an option (no SD card slot, but more storage than anything else in its price range).

You probably already knew but there are three replacement tips included in the package with the Muses.

I know the Wacom Intuos LP190K doesn't work with the Muses. I had to return it. I temporarily lost my Muses stylus (found it couple of days later) and found that the Samsung Note 4 stylus works. You can get 2 for $8 on Amazon. I bought these :

FUNKID Stylus Pen for Samsung Galaxy Note4, S Pens for Note 4 (Black-2)

My understanding is that Samsung Note2 styli work also, Probably more Note versions also, just not sure. The only minor drawbacks of these is that they are much smaller than the original stylus and you can't erase by using the end of the stylus.

Also goodereader.com sells direct replacement styli for the Muses for $36. They may sell tips separately also, not 100% sure.

I use this C to C cable and it's worked fine for me. I think it has to be the USB 2.0 version and no fast charging.

I haven't tried transferring files with it though because I use the one provided in the box and leave it plugged into my PC. I could try when I get home from work in the evening.
