That the corners then also made of PVC are a different color and Oberflächenstrucktur is really poor.
As such, the channels are really top, super to install, look good, valuable, in principle five points. But what makes a product manager since it black clip and which marketing managers such sticker and together they save at the corners. Recommended to those responsible: The stuff at home and watch it by myself attach. Order Not just in China.
Otherwise but still xmal better than the Plasik channels of Obi. But also xmal expensive.
