Practice, although just on a shelf spacing 12.2 "

Two caveats, however. On one hand, it is possible to use it with a large format tablet (12.2 "), the spacing is very fair and tablet fits, but with difficulty. Moreover, this stabilizer is opaque over its entire width with no hole for a tablet on central camera. So, my tablet is to be shifted, rather than centered to a photo or video taken with the rear camera. It is not a drama, but the overall imbalance, making it much less practical guidance.
