According to my experience, this handheld personal treadmill is a lifesaver for parents who spend endless hours on their computers. The compact size and USB-port compatibility make it easy to incorporate into your work routine, while providing a full-body workout. The sturdy build quality and quiet motor ensure a comfortable and effective workout .The only downside is the lack of adjustable speeds but it's not a deal breaker considering its other benefits. Highly recommend for busy parents who want to stay fit while staying productive at their computers!
