For almost 6 months I have shell always in use and it still holds! The Galaxy Note 10.1 (old version) fits very well and holds it in place, without that it can slip away. Also you get good at the S-Pen and the charging port. The rotation mechanism is running smoothly and without problems to the degree 360. Only through that many folding starts here and there a fold to be deeper and could in the long run may lead to damage. But at this price well justified and after nearly one year of intensive use normal I think.
