Have a HoverBoard to dispose of? Magnum Computer Recycling in Pennsauken at 856-333-0991. They will take the entire unit. The resident should NOT dismember them. Magnum will give you a certificate of destruction you need to get your refund. They only request you call before going to Magnum.
Please do NOT bring them to any of the County Household Special Waste events as Clean Venture will NOT accept them. So far, Magnum is the only outlet we know of in South Jersey.
