Hello AAlima, thank you for your comment. We currently ship to the US and Canada. Many of our overseas customers use Freight Forwarding services to ship our chairs.
I was given this machine and extra batteries. The batteries do not have any charge at all and no lights come on- on the machine( the light on the cord is on). Do they just require a long time to show a charge?
