Catastrophic !Very poor and weird customer service. They are not tired not to solve a problem. For the products by third party suppliers, they don't provide support at all.I contacted their customer service service and the vendor several times, without any solution. They don't care and find a solution.For the products not sold by Amazon the service quality is definitely lower than the products they sold or send directly. However, there is no indication that there is a difference in service quality and that we can experience problems more frequently than the products Amazon sells on its own. That is deception of the Client.Also there is always a problem with the products which are ordered from Germany, but always. Either the postal services write the address wrong and they don't deliver the product but pretend so.
