Overview
Not a hydraulic cylinder rower, this Sunny machine uses magnets to resist an alloy steel rail and a contoured seat. A digital monitor tracks time, distance, stroke count and calories, and transport wheels help you roll it away.
Magnetic resistance and a long rail give a smoother, quieter stroke than a cylinder machine, and the frame stands up when stored. The limitation is that it is still a battery monitor with a basic readout rather than a full smart console.
Who it's for
Apartments and spare rooms where noise matters and floor space is tight, with the app available for optional tracking. Competitive rowers and anyone wanting a big screen should consider a higher-end machine.
Pros and cons
- Quiet magnetic resistance
- Long rail for stroke length
- Basic LCD monitor
- Seat and rail details sparse
- App is optional only
Performance notes
Magnets resist the flywheel without contact, so the effort rises smoothly as the tension level is increased and the stroke makes little noise. A longer rail lets taller users complete a full leg drive. The monitor counts strokes and time from a sensor, so calorie numbers are estimates.
