Does not even deserve the one star - shame that no negative - can be awarded stars.
Update:
The company Handynow was very very helpful and gave me a replacement sent FREE OF CHARGE. The plugs were better processed in the second delivery, but you have to squeeze firmly the plug when plugging and unplugging, otherwise the metal part dissolves again.
An employee of the company Handynow called me today and told me that the supplier has been changed and a third free delivery has been initiated .... I call customer service!
