I have not yet received the invoice. FedEx is trying to charge the item to a private individual's account, which is a significant loss for me. I couldn't find any way to make a corporate purchase on the website, so I entered the company name and tax number in the billing information field next to the person's name, but it seems that this was ignored. In addition, the website does not indicate that the purchase is not being made within the EU, which means that customs duties and VAT are added to the prices. I think this is misleading. I cannot comment on the product yet, as I will receive it in about a week, assuming I can somehow arrange customs clearance by then.
