Saeyang Marathon Mighty + SH20N Review UK (2026)

The Marathon Mighty sits in an interesting spot in the Saeyang range: genuine Korean-made Marathon engineering, the same light SH20N handpiece as the £240 M4 Lux, a Twist-Lock chuck — and a foot pedal in the box — for £192.

If the Champion is the range's benchmark, the Mighty is the quiet value pick.


Quick Verdict

You get the core of what makes Marathon drills liked in UK salons — smooth 0–30,000 rpm control, forward and reverse rotation, and a light, well-balanced handpiece — without paying for design extras. The Twist-Lock handle means one-move bit changes, and unlike some rivals at this price, speed can be controlled from the base or the included foot pedal.

Best for: Techs who want genuine Saeyang quality on a tight budget — and a foot pedal without paying extra. Compare with: Champion Black + H200 at £165 — the classic pick, but no foot pedal in the box.

What Stands Out

Twist-Lock, No Tools

Bit changes are a one-move twist — no keys, no spindles. On cheaper drills this is where corners usually get cut; here it works the same way as on the more expensive Marathons.

Foot Pedal in the Box

Most drills at this price make the pedal an optional extra. The Mighty includes it, so you can keep both hands on the client's hand from day one.

Light SH20N Head

At 148 g the SH20N is one of the lighter handpieces in the range — noticeably easier on the wrist across a full day than heavier pro heads.


Pros and Cons

Pros
  • Genuine Saeyang Marathon build at £192
  • Twist-Lock bit changes — one move, no tools
  • Foot pedal included as standard
  • Light 148 g SH20N handpiece
  • Forward/reverse with smooth 0–30,000 rpm control
Cons
  • Simpler base than the Champion — fewer refinements
  • 45W / 30,000 rpm — not built for heavy acrylic debulking all day
  • EU plug with UK adapter (not native UK plug)

Who Should Buy This?

Buy it if:

  • You're starting out or equipping a second station on a budget
  • You want a foot pedal without buying it separately
  • Light handpiece weight matters to you

Consider the Champion Black + H200 instead if:

  • You prefer the classic H200 workhorse handpiece and don't need the pedal

Final Verdict

The Mighty does the unglamorous thing well: real Marathon quality, sensible accessories included, and a price that undercuts most of the range. For everyday salon work it covers the fundamentals with nothing missing that matters.

Rating: 8.7/10 — the best-value complete package in the Saeyang desktop range.
