I placed an online order for model H hybrid I received chair in beat up pkg, could have been a previous return judging by the packaging. I paid better than $200 for upgrade from 6Ah battery to 10Ah. I received 6Ah battery only. I called the company today, they blamed health crisis for 10Ah backlog. They stated when they received more 10Ah batteries in April they will send me one. I don't trust they will do that, otherwise I would have been notified at time of shipment.
