Not as good as Ugear or Rokr. But good. Slowly I needed 12 hours. The instructions are often quite opaque. Just as many "toothpicks” have to be smeared and used and cut, which was sometimes difficult. Also after disassembling the locking mechanism to check if the gears are installed correctly? It does not lock and opens at any time. That made me angry. Too expensive / something to gain, something to lose. It's nice when finished, too bad it doesn't block. 3 stars for everything.
