Al momento non ho termini di paragone, comunque mi sembra bene.

This has better compatibility(when dealing with images used in the midst of text, like latin words) than most epub readers I tried(including iBooks on my iPad). The only alternative to this which I know has similar compatibility, is an app called Marvin on iPad.

Considering the competition... Rated 3 out of 5 stars

Well, it's not bursting with features is it? I'd sure like to be able to change the font, and its barring of whole-document search is a pain [must search chapter by chapter, sigh].
On the other hand, user-friendly/ergonomic epub readers are very rare [CoolReader was only tolerable one for me], and it IS free, so i'm grateful for it.

Days later: stopped working. Just get "Connecting...." lockups. Oh well, CoolReader was better anyway.

Simple and works well Rated 4 out of 5 stars

Great. Allows you to read books / EPUB files on your browser, no spyware, no hassle, simple and to the point.

IMO the only things missing are 1) night time reading mode; 2) page number estimate / display and 3) conversion to PDF tool.
Apart from that, the good points: fast and stable; crossplatform; simple GUI and options for changing text size, and has a good library management tool.

Nice, but... Rated 3 out of 5 stars

Doesn't seem to have any way to show page numbers or skip to a specific page. Pretty useless in that regard.

A nice addon . It can be used on any operating system (crossplatform)

simply does the job and you don't have to download a heavy software. Just about 250 KB.
I wish the fonts were somehow smoother like in pdf viewers.

Thanks!

Pretty Good, but....... Rated 3 out of 5 stars

It seems to do a decent job, but 2 caveats so far.
It puts a "catalog" icon to the left of the "Home" icon, and you cannot change it in any way. 2 Problems:
1) This disabled the downloads access (The arrow is gone)
2)The "hotspot" is active even in the full screen mode when the icon is invisible. If you mouse over the hotspot, the screen jumps all over the place.

They're deal breakers for me, but many of you may not care.

Good but... Rated 4 out of 5 stars

I can't find where to change interface language to English

Good for night time reading Rated 5 out of 5 stars

I've been looking for a reader that allowed user choice of background and text colors. I could not find that feature in other readers, such as Adobe Digital Editions and Sumatra PDF. But this one does it! Now I can read in the middle of the night and not wake up my dear wife.

I cannot comment further, but just had to add my thanks for this particular feature.
