I’m not a big fan of Chinese sites selling devices that have been sold for a while in the US. It’s hard to know what sort of quality you’re getting and it makes troubleshooting difficult if something goes wrong. The Complex 11t is a great example of this; it’s been sold as the Cube i7 Stylus in other places and has been changed a bit to fit FCC regulations. It now sells as the Mytrix Complex 11t and is sold with a keyboard and stylus, making it a viable alternative to Surface Books and Pros for people on a tight budget.
You can buy this tablet directly from desertcart, a company that has been operating since 2014 and sells in 164 countries. It’s a legitimate site and has high marks on customer review portals. This tablet comes with Windows 10 Home and no extra bloatware, which is a relief on low-end devices that tend to come stuffed full of crap. The stylus is a standard Wacom Feel pen and performs well on the screen, though it doesn’t have the broad pressure range of the Surface Pro pens I’ve used in the past.
