Problems, parts and running costs

Summary

A fold-in-half under-desk walking treadmill that stores against a wall or under a bed, quiet enough that Tom’s Guide heard shoelaces on the belt over the motor. Check which version you are buying: the A1 Pro name has covered both a 220 lb and a 300 lb machine.

Strengths

  • Folds in half, so a usable walking surface fits under a bed or flat against a wall.
  • Tom’s Guide found it quiet enough that shoelaces hitting the belt were more noticeable than the motor.
  • The remote is easy to use, and Tom’s Guide preferred it to the app.
  • The current version is rated to 300 lb, high for a compact walking pad.
  • A long-term owner reported the A1 Pro still running after more than a year and said they would buy the brand again.
  • Maintenance is basic: belt alignment and lubrication plus keeping the folding joint clean.

Weaknesses

  • The KS Fit app is unreliable; Tom’s Guide logged sync failures and mismatches between the deck display and the app.
  • The same model name has covered a 220 lb, 1.25 HP version and a 300 lb, 3.75 HP version.
  • Walking only, not a running treadmill.
  • One owner reported heavy vibration around three months and a long support exchange before return service.
  • No component-level parts catalog and no clear current warranty language are exposed by the sources.

Full research notes and sources

Which version you are buying

Tom’s Guide tested an older unit rated to 220 lb with a 1.25 HP motor and a 3.5 mph top speed. Current 2026 sources describe a 300 lb machine with a 3.75 HP brushless motor. Both have been sold under the A1 Pro name, so compare weight capacity and motor figures on the exact listing before you compare price or performance.

The app and the controls

FootSense automatic speed control and app tracking are the convenience features, but Tom’s Guide found the app unreliable enough that the remote was the better way to run the machine. The treadmill itself was easy to set up and quiet in use. Current apartment-focused testing describes the A1 Pro as comfortable for longer desk-walking sessions.

Maintenance and ownership cost

Belt alignment and lubrication and keeping the folding joint clean are the normal upkeep items for this kind of treadmill. No replacement-parts catalog or exact warranty wording is exposed in the sources, so an eventual belt, motor or controller repair is the main ownership risk. There are no subscription costs. WalkingPad lists the A1 Pro at $529 during an October 2026 promotion against a $699 reference price.

Is it worth it

The A1 Pro is the pick when you are heavier or walk under the desk for long stretches and want the wider belt and the 300 lb rating. Buyers who do not need that capacity can save money and weight with a C2 or Z1-class model. The $529 promotional figure is WalkingPad-direct, not a standing street price, so confirm the exact revision before ordering.
