Well ... After less than one month break

I received this product from Winten as a gift, otherwise I would not buy anything more from this company (previously had this battery tube that was graußig).
In principle, a great product idea, but poorly executed:
After less than 3 recharges the Lightning connector is already terminated by the board (is maintained solely through tiny solder joints). Thus, I would be no recommendation for a "hard use" off the desk, as a minimum bend enough to make the plug broken. How can you sell the so unstable cramp?
