This ereader is equipped with the 6" Pearl E-ink screen that most US ereader makers have long since stopped using on their front line models. This venerable screen has a resolution of 800x600, which as any owner of a Nook, Kobo, or Kindle Touch can tell you is more than adequate to let you read ebooks.
The frontlight has 8 brightness levels, from off to full power. Illumination is carried out by a special plate with eight LEDs mounted around the screen. There's no estimate on how the frontlight affects battery life but with the light off this ereader is specced to offer a battery life of more than 9000 page turns.
This is a budget ereader so it doesn't support audio, but the TB-416FL does support common (and uncommon) ebook formats like FB2, EPub, PDF, PDB, Mobi, CHM,, and DJVU. It can also read a number of office doc and other formats like RTF, DOC, txt, and html.
In terms of software the TB-416FL lets readers change the font size, save and delete bookmarks, rotate text, and reflow PDFs. There is also a Clock, Calendar, and file manger.
The TB-416FL has 4GB of storage, a microSD card slot,a g-sensor, and is available now with a retail of 3990 rubles (~$123 USD).
