Very happy with the product. The quality is excellent, very pleasant material, hits the keys on the keyboard also. Only small problem it is actually the @ that should only be used in qwerti mode or with the keypad on the screen. Although it's a shame, ultimately it is not so annoying I use for my part the screen keyboard that appears or disappears into a touch tablet (text box and return key). Yes, to use what I have read in previous reviews, the keyboard of the Samsung fortunately disappears (not automatically), but is still active! I recommend this product follows me everywhere in a meeting!
