my old network, which has been made with rubber cable clamp strip, has the harsh winter with extreme temperature fluctuations did not survive (the rubber is cracked in several places). Because this network was not so expensive, I afforded a new one. In the manual is that you the power to only 500g !!! may be loaded. But I do not need power. But I dared often pack into deutlichst more and lo and behold it holds out. It also makes an overall very stable impression. The attachment If you secure the power permanently to the car okay. But since I have a stroller with swivel bracket, I use the network only for specific purchases. Then the fastening and loosening of the network back is annoying. It needs to min. 4 max. 6 Make a loop be hooked into an anchor, which sounds easy, but through the narrow anchor and the thickness of the network already requires a bit of patience, which you do not always applied as Mama in shopping stress.
