the keyboard arrived distorted. The store refused to refund. At the end aliexpress refunded me.
The keyboard is slightly different from the original: -sides of the backplate are not black (that is only cosmetic, as you only notice when you look verticaly on the keyboard), -I had to use the original flatcable from the laptop, I had to cut a few tenths of a millimeter from the width of the flatcable to make it fit the connector on the keyboard. My laptop is Dell Latitude E5520. Shipping 4 weeks; that is fast considering the Corona crisis delays that I experience with other items. Value for money ? : yes
The keyboard works fine.
