This bag is in my opinion very solid and shows even after several months of use no signs of wear. It lies with the Kindle comfortably in the hand and also the reading with one hand, made possible by the 'grip' on the back, is very useful and innovative. The Kindle is of course through the pocket a lot wider and heavier, but this falls at least for me not unpleasant. An average book can not keep up!
For me, the protection factor is through the pocket also suitable for transport on the road. Unless you're moving bricks in your backpack / shoulder bag of the area, the Kindle in the Tuff-Luv bag is well protected and can be transported with other things quiet in backpack / shoulder bag.
Based on the good processing and the innovative idea of reading with one hand I give the bag 5 Stars. Another positive aspect is the manufacturer's lifetime warranty on materials and workmanship.
