Is Nexo banned in the US?

Could you please enlighten me on the legality of Nexo in the United States? I've heard rumors that it might be banned, but I'm not entirely sure. Could you clarify the situation for me? Is Nexo indeed prohibited for use in the US, or are these just misunderstandings? If it is indeed banned, could you explain the reasons behind this decision? And if it's not banned, could you provide any assurances or evidence to support this? I'd greatly appreciate your help in clearing up this confusion. Thank you in advance for your time and effort.
