Even after many months of using the device shows no signs of wear. The change of sides takes place quickly and reliably. The lighting is pleasant and neither too bright nor too dark. Pushing a button allows the lighting adapted to the circumstances. The memory of Tolino is able to store large enough to many Ebooks. The only point that bothers me is the battery indicator. They often weigh in a security, to report only briefly that the battery is empty, so a point deduction.
