Prolonged charging cable was needed!

I desperately needed a longer charging cable for my phone and found it on Amazon!
Up to 2m this spiral can be stretched. It took just under 1.60m for my purposes.
When trying out I was a little disappointed with the high tension of the cable. In order to achieve my desired length, I had to stretch quite far the spiral. Immediately I had a great concern tension persisted over time. The cable material is much too rigid and inflexible. The plug is pushed to one side or slips out of the socket. Also arises the mobile lateral pressure and the plug slides out when it is not permanently recorded!
I had already used different spirals of devices that were much softer when it comes to the cable. It would have to respond to strain much more easily and without much tension.
Again I would not buy this charger, at least not as a spiral!
