It is not a Dremel. And most definitelly not with a capital “D”. It is a Tacklife generic rotary tool.
A Dremel is a brand.
You do not call every copying machine a Xerox, you do not call every chainsaw a Stihl, you do not call every car a Ford. Some people might, in a colloquial manner, but not on an official site when you are trying to hawk said product.
By the way, Proxxon makes much better rotary tools (and higher quality accessories) of this type than Dremel.
