A quiet, magnetic-resistance rower with a longer rail and a solid tracking display, worth considering if smooth, low-noise operation matters more than gym-level resistance at the top end.

Overview
The Sunny SF-RW524079 is a magnetic-resistance rowing machine with a dual-track rail, 16 resistance levels and a 300-pound weight capacity, built for full-body cardio at home. It's aimed at buyers wanting a quieter, app-connected alternative to hydraulic rowers.
This model uses magnetic resistance across 16 levels rather than the hydraulic cylinders found on some other compact rowers, generally giving a steadier, quieter pull. The 45.7-inch slide rail and 40.9-inch max inseam are sized for fuller leg extension than shorter rowers allow. Reviewer feedback referenced for this listing covers Sunny rowing machines broadly and touches on assembly, quietness and long-term use rather than every specific feature of this exact model.
- 16-level magnetic resistance system
- 45.7-inch dual-track slide rail
- Real-time stroke, pace and calorie display
- 300 lb weight capacity, padded seat
Who it's for
Suits someone wanting a quiet, magnetic-resistance rower with real-time stroke and pace tracking for home cardio sessions. Taller users should note that reviewers of similar Sunny rowers found the handle position a bit low and top resistance levels lighter than expected.
What buyers say
From Amazon customer reviews.
Reviewers of Sunny's rowing machines consistently describe the rowing motion as smooth and quiet enough to use while watching television, with assembly usually taking well under an hour thanks to labeled parts. Several noted the workout is more demanding than it first feels, especially past the first few minutes, and one long-term user reported losing significant weight through regular use combined with diet changes. A recurring complaint was that even the highest resistance setting feels lighter than expected, and one taller reviewer found the handle position sits a bit low relative to higher-end machines.
Strengths and trade-offs
Drawn from this product's published specifications.
- Quiet magnetic resistance across 16 levels
- 45.7-inch rail suits a fuller leg extension

Performance notes
Magnetic resistance across 16 levels is designed to shift smoothly between intensities without the abrupt jumps some cable or hydraulic systems have. The 45.7-inch dual-track rail keeps the seat aligned through the stroke, and the display tracks time, distance, calories, strokes, SPM and 500-meter split as you row. Reviewers of similar Sunny rowers describe assembly as straightforward, often under 30 minutes, and note the machines run quietly enough to watch television without raising the volume.
