“I can't begin to tell you how in the past 7 months my life has changed. Transferring in and out of my car for my daily commute had become more difficult due to the weight of my old wheelchair, this became no longer a problem thanks to the Sub4. I have rediscovered my love of travel and have increased my independence to a level I never thought was possible.”
George Costigan
