Product of very poor quality, very short lifespan

I can still use it, but this blockage, the phone is less well maintained.

Too bad, because apart from this weakness, the rest seems tough (electromagnet rotation system and orientation of the support, quality telescopic arms ...)

Updated: May 15 Today, about 5 months after purchase, the plastic tab in the cup just let go ... That says a lot about the quality of the product. Avoid, therefore: not very expensive, but it's really the Quincaille plastoc!
