Thank you very much for your valuable feedback! We always highly value the opinions of each and every one of our customers. We contacted you at the very first moment we received your feedback and communicated with you to resolve the issues. Regarding the EMS machine you mentioned, it has sufficient therapeutic power and usually, significant results can be observed after completing 3-4 standard sessions. Also, regarding the condition of the surface of the machine shown in your pictures, please be assured that this is not a paint issue, but rather traces of residual oil and wax cleaner. This is to make the surface of the machine look brighter. We have sent you a detailed video of the cleaning operation. In the meantime, we would be happy to arrange a video call to show you the correct cleaning method online and answer any questions you may have.
