This is a very effective piece of equipment depending on your needs and goals. You may have to adjust to the nonstop movements required to operate this device (YouTube). As a runner I have used this as a regular part of my injury prevention and rehabilitation regiment for the past 5 years. It is expensive but they do go on sale, and I’ve seen them on facebook marketplace (occasionally). If you get one I recommend buying an assortment of flywheels, wall storage system, and use your regular cable attachments. I have continued to find use for it in my endurance training and as an accessory to strength exercises. The build quality is excellent and I haven’t experienced any issues with the equipment.
