Great amenity for community!!

SUMN is a very user friendly application. I never have to own a car again which saves me so much $$! Moving to Miami soon and hope to have it there as well.

Quick. Convenient. & NO gas

This has been a lifesaver in my community. I’m so glad that they chose to launch here first! No regrets not having a car of my own.
