I did not purchase the Revain device that I have. But I can say that I am very satisfied with my device. It limits the tracking of my steps from April 18, 2016, which is more than 30 days. I like the different modes that appear at the touch of a button. Because of the benefits of using this daily pedometer, I bought a Revain device for a friend that I will be gifting to her very soon. I hope she will use this device to become more active. I gifted my daughter a device I bought at the clinic and she has been using it for about 2 weeks with great success. I highly recommend this device as a tool to help you see how active you are on a daily basis. Walking doesn't cost anyone but time. Walking is a natural function so I wouldn't consider it exercise. Back on topic, I recommend using a device. It's easy to use once you've entered all the required information like your stride length, etc.
