Only negatives:
1) the holder with the suction cup is a space-saving: the whole hides part of the driver's attention area, which is a bit disturbing during certain maneuvers. But honestly, this is somewhat the case with most products of this type.
2) the "ventilation outlet on clips" does not set the device enough: everything moves with the car's movements
But overall, I'm satisfied with the product. Negatives mentioned are "light".
Small side note: do not try to move the sticker bracket supplied with the product. I tried. Unfortunately, part of the self-adhesive surface has come off when removing it from the original location. So if possible, although réféchissez on location before installing this support. You may not get a second chance :-)
