Unfortunately, quite often it confuses the keys and when you change the language on the tablet (e.g. from English to Greek), it continues to write in the previous one. Obviously, a bug of Apple because it is not an authentic Apple product.... funny....

Sometimes the trackpad stops working and the tablet needs to be restarted to fix it... and I consider this a bug of Apple

It is worth its money 100% from all perspectives.
I won't say much since anyone can see reviews on YouTube, but my opinion is that if you're considering it for a keyboard case, etc., don't hesitate. I've had it for 2 months and it's worth every euro.
