I've been a Blackberry user for many years mostly due to its EXCELENT physical keyboard. Last 2 years I used Q10 which is a great phone but decided to change for many reasons (some aps won't support BB anymore, need better camera etc). I was considering Blackberry Priv but I don't want to slide that keyboard in and out 1000x a day so I was looking for other options. Another BB anroid phone may be out only at the end of this year (if so) so I was very excited to see SAMSUNG started manufacturing basically BB qwerty keyboard that can be attached to S7 or S7 Edge. This keyboard is definitely an outstanding option for former BB users but I gave it 4 stars due to a fact it's not backlit (in dark you can't see anything at all, the display does not make it lit enough) and although it feels very solid it feels little "rubberish" comparing to original BB keyboard that feels almost "slippery" and your fingers slide easily at the surface for super fast typing. I hope they will manufacture upgrade that would be backlit connected to BlueTooth and use smoother materials for actual keyboard surface. On the other hand the positive thing is you have better grip on it. Overall, I'm very happy with it because to have a Samsung s7 with it's top notch specs and physical qwerty keyboard in this combo is a great option!
