I’m very pleased with it. Good device. I take it to work as well. First it didn’t help much. Then I did a bit research on the sound wave shock therapy and found out if my blood circulation is bad nothing going to help. So I started elevating my leg with couple of pillows while putting Plantarcure and kept the leg elevated through out the night. Wow, what a big difference. From 6 months of no exercise to slowly I’m getting back on my cycle machine. So if the Plantarcure doesn’t work, don’t give up check for your blood circulation and then try Plantarcure. I am very pleased with Plantarcure. It doesn’t take that much battery power and snaggle in my handbag.
