Google Randy's Mobility Coupon, there is $10 off a week. I did a 5 day once and they gave me the $10.
THere are less expensive rentals, but no where did I find the service, for especially first timers for set up break down, how to put back together, charge, take the keys off, turning off, the basket and long battery charges.'AND great instructions for using the unit.
Never needed customer service at all.
