After unpacking the goods, to which there are no complaints, as well as to the general appearance of a well-packed product, I received a poor quality instrument: three notes do not correspond at all to the declared characteristics. I recorded a video, sent a request to the company, wrote in all chats, according to the company's policy, and after 14 days no one contacted me. I will in every way contribute to the initiative to leave negative reviews about this manufacturer in the future.
