Its the VT 007. The guy has a lot of info on Amazon and a separate site. His CS is great. At least read his info to understand what you should be looking for. He explains well. It costs 399$. Make sure you get LINEAR vibration. And compare the specs w Marodyne. On one end of range VT matches it but you can increase if that works for you. Plus the guy behind it knows fitness. The Maromen and their ads were so cringey, like car salesmen!
