Buy the WalkingPad A1 Pro if your cardio goal is daily steps and long, low-intensity sessions you can do during calls. Buy the Sunny mini stepper if your cardio is short interval bursts and your storage slot is a closet corner, not a wall. They are both apartment-quiet; they serve completely different training days.
Session shape
The pad walks you for an hour at a natural gait while you work. The stepper works you hard for ten to twenty minutes in intervals, which is what its small hydraulics are built for. Match the tool to the session you will actually repeat daily.
Storage shape
The pad folds to a flat panel needing a wall lean, a bed slot, or a door gap. The stepper is a 16 in cube that fits a closet corner as-is. Small homes should measure which shape they have spare, because both claims are honest and both are useless in the wrong slot.
Maintenance profile
The pad asks for belt centering and a clean deck. The stepper asks for pivot lubrication and bolt checks. Both are minutes a month; neither is maintenance free, and owner complaints for both trace back to skipping those minutes.

FAQ
Questions, answered straight
Which is quieter through the floor?
The stepper, by a hair, when its pivots are maintained: no motor, no belt, soft hydraulic motion. The pad is a close second at walking pace. Both are far quieter than any running or jumping work indoors.
Can either replace outdoor walking entirely?
The pad comes close for step volume in bad weather and busy weeks. The stepper cannot; it is an interval tool. Honest apartment cardio plans usually pair one indoor tool with outdoor walks rather than replacing them.
Which is better for heavier users?
Check both listings' user weight limits before ordering; capacities differ by model revision. As a class, a full deck distributes load more forgivingly than two small pedals, so heavier users generally find the pad the steadier platform.
