SmartDrive MX2+

SmartDrive power add-on compatible with E3 watch or Apple Watch.

Game changer. I found it works best with the Apple Watch versus E3. Considering trying the new SpeedControl Dial in the future.

Very easy to use and great for reducing pain, fatigue, and increasing the length of time you are able to be out and about. You can feel some bumps, but it’s not too much vibration-wise for me. I can take it on and off my frame from my chair, and its magnetic attachment for the charger makes plugging it in really easy.
