Criticized: overall performance and screen reliability.
Review summary
Written by Augur from the 8 reviews analyzed
This 21.5-inch all-in-one computer with a 4K display is intended for basic office tasks, but its overall performance proves to be particularly disappointing for daily users. Although the machine remains functional for very light use, it suffers from significant slowdowns that manifest right from the first uses.… The general slowness of the device heavily penalizes the user experience, while the screen exhibits a technical fragility characterized by the appearance of unwanted display lines.
