Originally it was FUTURE14000, but it seems that it was later changed to the product name FUTURE14000DX.
Since both medical device approval numbers (21600BZZ00384000) are the same, the output and efficacy of the device have not changed. The DX has a futon that can be energized at a low potential of 1400vp while sleeping.
If you don't need a futon, you can sell it without a futon.
