Chuwi AeroBook Pro Laptop Review: Core m3 is Showing its Age

Chuwi AeroBook Pro Laptop Review: Core m3 is Showing its Age

The AeroBook Pro is the 2020 refresh designed to replace the 2019 AeroBook. Despite what the name may suggest, however, both performance and the chassis remain almost exactly the same for no tangible year-over-year advantages.

Chuwi UBook CWI509 Tablet Review: The Surface Go Wannabe

Chuwi is at it again with yet another Microsoft Surface clone. This time, the Chinese manufacturer is targeting the Surface Go crowd with an 11.6-inch detachable. The end result has some respectable qualities, but it's a big miss overall.

Chuwi UBook Pro Tablet Review: The Microsoft Surface Pro Clone

The UBook Pro offers high-end looks with low-end performance for a mid-range price. If you can get past the slow Core m3 processor, then you'll find the super-bright 12.3-inch display and three USB ports quite useful when compared to the dimmer and pricier Surface Pro.

Chuwi AeroBook (2019) Laptop Review: A crowdfunded compact Ultrabook

Chuwi's latest laptop is the product of a successful IndieGoGo campaign. While the package is wrapped in a nice shell, the AeroBook ultimately falls short of other compact notebooks. This is largely in part to its outdated 6th-generation Core m3 CPU.
