Lousy engineering from steering column which is a real threat to life and limb, to Inability to "park" it without dumping it on the ground. Don't. Uy the cargo carriers meant to be attached over the wheels. These will bruise the he'll out of you on even the smallest bump - again, lousy engineering as no stabilizer bar. The charging module has been junk for years and segway could care less. I think they are going under as they have fixed none of the most serious problems, and according to one of our dealer's employees, have known about them for years.
A piece of junk with brilliant technology on a chip. August 2010, and we unfortunately have three of them.
