Regarding the following picture:
I would say there's no L3/R3 button, but I'm maybe wrong.
Whatever the result will be, I did order one last week and I'll share my impression and other details after reception and test if nobody has done it before.
The cool thing is that the video shared by vcoleiro1 is showing a well built product at first impression.
Only the spring noise at the end during the unlock process seems to be quite weak... Let's see what it will be when we'll have the item in hand.
