Way more than a e-reader
Perfect for reading, as other eink devices I used to have, but this device offers more than a reader is expected to offer.
First of all, it's fast, a tablet more than an e-reader.
It can streamline not only my reading habits, but I find it perfect also for office work; I use it to connect to my PC at home, and it's working fine.
I feel I can recommend it to everyone who needs to work in mobility with a trustworthy device.

A happy customer
Ordered this on 14.05.23 and it was shipped on 22.05.23. I received the package this afternoon (25.05.23) from UPS after a slight delay due to an unexpected glitch at their processing hub in my country yesterday. Everything arrived in excellent condition. I am very pleased to have found eReader.Store to make this purchase as it is more affordable than Amazon and a reseller in my country. The original Boox site does not ship to my country. As a writer and researcher who has been battling with dry eyes and migraines from LCD screens for nearly 2 years, I hope the Tab Ultra C, my first e ink tablet, would be a game changer. Looking forward to shift the bulk of my reading, editing, research and writing tasks to this tablet in future. I hope your store will consider carrying the Fujitsu Quaderno A4 with Kaleido 3 screen that is expected to be released this mid-June. Thank you for the excellent service.
