Hanvon Ugee

They have 3 subsidiaries for consumers: Ugee, XPPen, and Xencelabs. They do own a few other brands but those are generally B2B.

Ugee/友基

Ugee is their budget brand. The tablets they produce have many varieties of colours, and are generally quite cheap. It's likely their popular brand in China. (based on tablet sales)

XPPen

You probably already know XPPen, it's their most popular brand in the global market. It's their mid to high range tablet brand, and you can find a huge variety of tablets under XPPen branding.

Xencelabs/马蒂斯

Basically XPPen for professionals.

Also, don't buy their pen tablets. The XPPen Deco Pro Gen 2 tablets are pretty much a direct upgrade.
