I had been researching under desk treadmills for many weeks. I came across Vitality4life and contacted them by email. I got an email back which was very thorough and helpful. The range of options for these items is mind-boggling because there are so many different options. I contacted the support line and had an excellent conversation with a very helpful staff member. I ended up buying the walkslim 610 treadmill and I'm very happy with it. I purchased it during an incredible sale at 60% off so very happy with the purchase price. The product itself is excellent. I've only had it a short time but it is exactly as described. Works very well as an under desk treadmill and can also be used as a jogging/running treadmill if you lift up the handle. Fabulous support by staff, excellent product and equally great price. Thank you very much.
