It’s not a fake, it is made by HP. Also, it has value as a calculator, not just nostalgic sentimental value. It works just as well as the original.
I own one because a while ago I bought, one by one, iconic world changing calculators to collect. I like having physical history. This re-release seems like a very nice bookend to that collection.
It is not made by HP, it is made by Moravia Consulting in the Czech Republic under an official license from HP. HP's Calculator Division hasn't been a part of HP's actual org chart since before even the HP/HPE split. It's the modern world thing where corporate brand names stopped aligning with corporate org charts decades ago.
