I have a smart drive MX 2+ for sale. It comes with the watch and attachments for foldable and rigidchair. It has been used approximately 10 times. As a C4 quad I just cannot utilize the functions properly. It was my hope that I would be able to get permanently into a manual chair with this device. The reality is that my hand function is just not good enough to go through doorways and down hills. This device is definitely made for somebody who has hand function or a high-level quad. This is not me. Asking $2500. The unit is in Florida and buyer pays shipping. Had a hard time loading pictures. P.m. me for pictures.
