My full timing daughter has been extensively using the Travel Scoot for something like 5 yrs or so. She goes everywhere on it. Lithium battery seems to provide lots of power (it can really go fast) as well as staying power. It folds and unfolds very easily.
Late last summer she accidentally backed her motorhome over the rear of the scooter so when she visited me in FL, she ordered a new left rear axle/frame tube which the sent to her. I took the old apart and the new part fit just perfectly. I was impressed as I took the scoot apart with how well it was designed and fabricated. As to price - you get what you pay for and the Travel Scoot is not a toy. Based on the number of times I've personally heard people come up to her and ask her if she would sell it, I'm guessing it would hold value pretty well and be quite easy to sell.
