I originally bought this leg/ motion massager for my husband who has tingling and numbness in his feet. He has been using it a couple of times a day and says he thinks it has helped him tremendously. It really gets the circulation flowing and he likes that there are so many speed settings for when he needs a lighter vibration or a stronger vibration. He says it makes his feet feel great for several hours at a time! He liked it so much that I decided to give it a try. I have plantar fasciitis and I have found that this machine is helping to relieve my foot pain as well. The gentle or strong vibrations really help to relax my foot and have helped make my pain more manageable. The machine turns off after 15 minutes, but you can also set the timer to turn off sooner. There is a feature that alternates between the different vibration settings and it provides a variety of strengths. Or, you can keep it on the setting that you like or change it up or down as often as you want for the 15 minutes. It's been very beneficial for both of us so far. It is a bit pricey, but we feel the device is worth the money.
