I have only just started using so I can’t comment on how long it will last. Battery seems to last very well. 2 hours continuous use and the battery is still 3/4 full. Easy to operate. Reasonably easy to dismantle and put in car. A few minutes on initial set up to get seat height, arms in comfortable positions is well worth the time. The tiller adjusts easily to make it comfortable. Feels stable. Would buy again.
