Site administration is not responsible for the incorrect, unsafe operation of the devices by you and others, as well as for the unfair use of the information by third persons. All information provided on the website is for informational or promotional purposes. Site administration does not force you to buy and use the devices. The devices are not sent without payment, including cash on delivery - only after receiving your payment the parcel will be given to the post office. When paying you agree to transfer your personal data (full name) to Joint Stock Company "Russian Post" TIN 7724490000, which accepts, packages, transports and issues the purchased devices at the post office of your choice. Due to the inability to check the correctness of the use/operation of the devices you purchase no warranty is provided for any devices, except in cases where the warranty conditions are explicitly indicated on the full description page of the device or in the documentation for it. For the same reason and due to the impossibility of carrying out a technical examination of the integrity of the devices to find out the reasons for the failure of the devices and their electronic components (their internal plates, crystal and film structures), the devices you buy are considered technically difficult and cannot be returned or exchanged.
