Jeff participated in our Zeen usability study as we were refining the design. We have Jeff to thank for the Zeen's rear caster locks! He has continued sharing his Zeen experience with us and has been a Zeener for nearly a year and a half. You've seen him exercise (tips & tricks in other newsletters) and now you'll get to hear some of his Zeen story as he strolls, coasts and enjoys his hometown.
