ERGOLIFE sells one machine, a self-powered curved manual treadmill, and it is the cheapest credible entry in that class. At 26 inches tall and about 50 wide it will not fit under a desk despite the walking pad marketing, so it competes with TrueForm and the Sunny SF-X7110 rather than with pads. The curve supplies the grade, six magnetic resistance levels supply the load, and the armrests fold down for hands-free walking. There are no independent trust signals behind it, no BBB or Trustpilot profile and no organic discussion, and the hardware is likely white-labeled from an outside factory. The listing has also been out of stock across several checks and has burned through three ASINs.
The most affordable credible curved manual treadmill in this comparison. It's self-powered (no motor or electricity), with foldable armrests and 6 magnetic resistance levels. Note this is a standalone curved treadmill, not an under-desk pad - at 26" tall it won't fit under a desk despite the "walking pad" marketing, so it competes with the TrueForm Trainer and Sunny SF-X7110 rather than slim under-desk pads. The brand is legitimate but unproven.
