I had bought the phone in February 2014 for a stay in the USA in June 2014. Delivery was all ok, functions well, only I unfortunately could the US SIM card here in Germany not to try. In the US, it turned out that the device does not detect the card and I therefore could not use it. Had then after my return with buying club on Amazon contacted and had greatest concerns because the company is based in California yes. In fact, buying club has reported immediately, it took place div. Correspondence, I have the equipment returned and got within a short time a new, functioning unit. Above all, the sound and the ease during the entire process can only be described as totally customer focused and I have something rarely experienced in complaints, which is why I only company buying the club can recommend to anyone, because can happen always something, but with buying club has a supplier who maintains a truly cooperative relationship well beyond the sale to its customers. This company is thoroughly recommended as a supplier.
