Saeyang Marathon 3 Champion + H37LSP Review UK (2026)

Same control unit and same core performance as the popular H35LSP set. The H37LSP delivers 35,000 rpm and 3.2 Ncm torque — identical to the H35LSP — and is the handpiece Saeyang positions for nail techs whose work leans toward gel systems and acrylic filing, at the same £180 price point.

If you're deciding between the H35LSP and H37LSP, this review explains what's actually different between them (and what isn't).

Quick Verdict

The Champion + H37LSP matches the H35LSP on every performance spec — 35,000 rpm, 3.2 Ncm torque — but it's the handpiece Saeyang positions for gel and acrylic filing work. At £180, identical to the H35LSP, the choice between the two comes down to preference and use-case framing, not raw performance.

Best for: Nail technicians who want the handpiece positioned for gel and acrylic filing work, at no extra cost.
Compare with: Marathon 3 Champion + H35LSP — same control unit, same 35,000 rpm ceiling, same 3.2 Ncm torque — the all-round option.

H37LSP vs H35LSP — What's Actually Different

Both handpieces mount on the same Marathon 3 Champion control unit and share identical core performance:

The performance specs are identical — Saeyang positions the H37LSP as the dedicated option for gel and acrylic filing work, with the H35LSP marketed as the all-round choice. In practice, both handle the full range of nail tech services equally well; the difference is in marketing positioning and a few grams of handpiece weight, not raw cutting power.

If you're unsure which to pick, either is a safe choice — go with the H35LSP for the lightest possible handpiece, or the H37LSP if you prefer the gel/acrylic-focused option in your kit.

Performance

Hard Gel and Acrylic

Handles hard gel overlays and acrylic removal at 20,000–25,000 rpm with consistent, controlled speed — the same performance you'd get from the H35LSP. This is simply the handpiece Saeyang positions for this kind of work.

Natural Nail Prep

Just as capable as the H35LSP at low speeds — precise and low-vibration for cuticle work.

Gel Polish Removal

Efficient, with consistent torque at mid-range speeds — no difference from the H35LSP.

Extended Sessions

Comparable heat and vibration profile to the H35LSP. For mixed services (some acrylics, some natural nails), you won't notice a difference between the two handpieces.

Pros and Cons

Who Should Buy This?

Buy the H37LSP if:

• You want the handpiece Saeyang positions for gel and acrylic filing work
• You're setting up a kit and prefer this option to the H35LSP
• You want the same performance as the H35LSP with no price difference

Buy the H35LSP instead if:

• You prioritise the lightest possible handpiece for all-day comfort
• You prefer the all-round positioning of the H35LSP

How It Compares

Final Verdict

At the same price as the H35LSP, the H37LSP is a solid pick for nail techs who want the handpiece positioned for gel and acrylic filing work. Performance-wise, it's identical to the H35LSP — the choice comes down to preference, not capability.

Rating: 9.5/10 — matches the H35LSP on performance and value.
