TechRadar's verdict comes from an X4 Pro owner who ran the numbers on every model — and an unlaunched S4 that already sounds promising complicates any decision made today.
Four devices, one verdict. TechRadar has crunched the numbers across Xteink's entire mini ereader lineup, and it does so from a distinctive vantage point: the reviewer already owns an X4 Pro.
The range under examination spans three shipping models and one still to come: the X4 Classic, the X4 Pro and the X3, joined on the horizon by the S4. TechRadar's framing of the not-yet-launched device is telling — it sounds promising, in the outlet's own words — and its verdict on the hardware already on sale is equally pointed. None of the three available models is a loser: each brings its own advantages, which is exactly what makes the buying question harder rather than easier.
That ownership angle shapes how the comparison lands. A reviewer who has paid for and lived with the X4 Pro audits the rest of the range against a device chosen with their own money — a stance that tends to produce blunter judgments about rival models than a neutral test bench, and a more candid accounting of whether the Pro earns its place in a four-way shortlist.
The S4, meanwhile, hangs over the entire exercise. Buyers settled on the lineup as it stands must now weigh it against a fourth device that has not arrived but is already being talked up.
The practical upshot for readers is a decision tree, not a single answer. Xteink has divided its compact range finely enough that the X4 Classic, X4 Pro and X3 each hold a distinct appeal, and the number-crunching exists to map those edges onto concrete purchases. Whether the S4's arrival redraws that map — and where it leaves the three models already shipping — is the question the piece leaves open, and the one the range's next chapter will have to answer.
