Quantum Device ALL ONE 275 UFO All One Although it is no longer sold, it still performs well. I also own several other wave devices, which I mainly use remotely, so I am selling this one that I no longer use. The ALL ONE is worn on the arm. I purchased it from the Japanese general agent. I contacted the agent and they said they can handle the name change. 100 guest registrations are unused, so you can use them as is. How to use: It works in conjunction with a smartphone app. Details are available on the web. Please search for "All One UFO 275". Retail price: 990,000 yen
