Saeyang Marathon 3 Champion + H35LSP
The UK's most popular professional nail drill setup. Marathon 3 Champion control unit paired with the H35LSP handpiece — lightweight, precise, and built for daily salon use.
| Specification | Detail | |---|---| | Max RPM | 35,000 rpm | | Handpiece model | H35LSP | | Shank size | 3/32" (2.35mm) — industry standard | | Direction | Forward / Reverse | | Speed control | Digital dial + foot pedal | | Suitable for | Manicure, pedicure, gel, acrylic, extensions | | UK plug | Yes | | Price | £180 |
The Marathon 3 Champion Control Unit
The Champion unit is Saeyang's workhorse — the same control box has been refined over years of professional use and is trusted in salons across Europe and the UK.
Digital display shows your exact RPM setting, so you can dial in precisely and repeat the same speed across clients. The dial is smooth and responsive — no jumping between speeds.
Reverse function is essential for removing bits safely and for specific nail prep techniques. It's a single-button switch, easy to hit mid-service without looking away from the nail.
Build quality is solid — the unit sits firmly on a work surface, doesn't vibrate across the desk at high speeds, and the controls are positioned sensibly for right or left-hand operation.
The H35LSP Handpiece
The H35LSP is where this set earns its reputation.
Weight and Balance
At around 90g, it's noticeably lighter than older-generation handpieces. During a full day of treatments, this matters — wrist fatigue is a real issue for nail techs working 6-8 hour days. The balance point sits naturally in the hand without needing to grip tightly.
Heat Generation
The H35LSP runs cool at typical working speeds (15,000–25,000 rpm). At maximum RPM for extended periods you'll feel some warmth, but nothing approaching uncomfortable. This is significantly better than cheaper handpieces that become noticeably hot within 20 minutes.
Noise Level
Quiet. At mid-range speeds (the range most nail techs work in most of the time), the H35LSP is noticeably quieter than cheaper alternatives. Clients notice this — a quieter drill is a less anxious client.
Precision
The low vibration at all speeds means you can work close to the cuticle and lateral nail folds without risking damage. For nail techs who do detailed prep work or work with nail art, this precision is essential.
White vs Gray H35LSP — What's the Difference?
Nothing technical — it's purely aesthetic. The white handpiece (H35LSP White) pairs with the white control unit. The gray handpiece (H35LSP Gray) gives a more understated, professional look.
Both are the same handpiece with identical performance. Choose based on your kit aesthetic.
Performance by Service Type
Natural Nail Prep
Excellent. At 10,000–15,000 rpm the H35LSP handles cuticle work and sidewall prep with the control needed for safe, precise work on natural nails.
Gel Removal / Soak-Off Assistance
At 20,000–25,000 rpm with a medium carbide bit, gel removal is fast and efficient without risking natural nail damage. The consistent torque at mid-speed is a standout feature.
Acrylic Filing and Shaping
The full 35,000 rpm is available for heavy product removal. Torque holds up under load — no slowing when working through thick acrylic.
Pedicure / Callus Work
Handles light pedicure work well. For heavy podiatric work (thick toenails, significant callus), consider the Cyclone-Vac or the ECO 450 at higher torque.

How It Compares
Final Verdict
The Marathon 3 Champion + H35LSP is the set we'd recommend to almost any professional nail technician as their primary machine. It's reliable, precise, comfortable for long days, and £180 is a fair price for what you get from a brand with Saeyang's track record.
The choice between white and gray handpiece is entirely personal — both are the same excellent machine.
Rating: 9.5/10 — the benchmark professional nail drill setup for the UK market.
