## Customer feedback

Customer feedback reports easy setup without driver installation, portability for travel, sharp-looking 1080p imagery, and improved multitasking for tasks such as spreadsheet and Word document work. Sturdy construction and a stable stand are also mentioned.

Aggregate ratings lean positive while still including a meaningful low-rating share, and the available evidence does not explain why customers rated it poorly.

- Positive themes: Feedback praises portability, display clarity, and usefulness for multitasking and office documents.
- Positive themes: Customers mention a sturdy build and stable stand.
