I was looking for the smallest, most lightweight, under-desk treadmill, with excellent ratings and excellent customer service. I have found all of that. (Please note: This does not "fold" as there is nothing to fold, no hand rails, etc.) The walking surface is enough space for me, and the speeds work for me. I will only be walking, no jogging or running for me. Because there are no hand rails, I would not recommend this for someone with balance issues, as there is nothing to rest your hands on, or to steady yourself. I worked directly with their customer service to resolve some issues and get my questions answered about a few things, as this is my first treadmill. They provided me with some of the best customer service I have ever experienced - they go beyond "above and beyond" - they really want their customers to be happy with the product; they go in depth with explanations and support.
