No published belt dimensions at all.This is the real hole. On a walking machine the belt length and width are the numbers you most want, because a short belt shortens your stride and puts the back edge closer than you think, and the width sets how much margin you have either side of your foot. Yesoul publishes neither. It publishes an overall footprint, but the walking surface inside it is left unstated — so the single most useful specification for judging fit is missing, and there is no way to check it short of asking the retailer directly.
No manufacturer model number. Yesoul does not publish a model number for this machine, which sounds like a footnote and is not. A model number is how you confirm that a review, a manual, a replacement part or a spec sheet actually refers to the machine in front of you. Without one, everything you look up afterward is matched by description rather than by a definite identifier, and that makes every later question harder to answer with confidence.
No published step-up height.How high you lift your foot to get onto the deck, every time, is not published for this model — the same gap almost every machine in this category leaves. And there is no published decibel figure and no published assembly weight, so “quiet” stays a description rather than a measurement, and how much of a job the setup is has to be taken on trust. The safety design is the reason to buy this machine; the missing belt dimensions are the reason to ask a question or two before you do.
