It didn't take too long for me to get used to. Maybe a week or two but it wasn't challenging either. My typing is much improved which was the goal. One improvement I would suggest is a red backlit keyboard because at night the white backlit can be a bit strong even at the lowest brightness settings. Obviously it makes the overall phone bigger but it fits in my pockets just fine.

My partner had been looking to recreate a blackberry style experience for many years - this has finally made that possible with a state of the art phone

The clicks on the keyboard are comfortable and easy to type and I never press the wrong key at all. I have created 42 keyboard shortcuts using iOS shortcuts and Clicks mode, so most of my work is completed using the keyboard alone. However, when using Japanese, there are many cases where "ー" is used in Japanese words, so a separate key is necessary. Also, it would be very inconvenient if there were not an icon to indicate whether the active input language is Japanese or English. If these two points are improved, I believe that the use of the system among Japanese people will increase significantly.

I've always wanted to have a BlackBerry when I was younger. When I finally got around to owning a BlackBerry, it wasn't more than 5 years that they decided to go Android and eventually fizzle out. So the iPhone I went. All this while, there was always something amiss with the iPhone and I always had missed the physical aspect of a BlackBerry from a typing experience. This, is the closest thing you will get to it. Build quality is good, the newer models for the iPhone 16 comes with better keys and clicks a lot better, more refined. But in any instance, this is really a job well done driven by passion. Amazing product that adds meaningful usability to an already great phone. It isn't perfect, nothing will be if it's not native or built-in, but this is the closest thing you'll get.

Sounds perfect.
