What is the 4.0 mm stroke best for?

Lining and bold color packing. The longer throw drives needles deeper and lays ink faster, but it makes fine shading and delicate detail harder to control.

Is it truly wireless?

Yes. The machine runs from a rechargeable battery pack instead of a cord and power supply, so nothing tethers it to the station.

Can a beginner use it?

Yes, though the long stroke rewards a steady hand. Beginners who plan to focus on lining and packing will get more from it than those learning fine shading.

Does it work for fine line or realism work?

Not well. A 4.0 mm stroke is too long for the small, controlled movements those styles need; a shorter-stroke machine is the better tool.

How does it compare with corded rotary machines?

It trades the unlimited runtime of a corded setup for freedom of movement. Expect to manage charge between sessions rather than work all day untethered.
