I'm interested in exploring your Exoskeleton walking aid robots, particularly the next-gen models designed for enhancing mobility for the elderly and those with disabilities. I would like to know more about the specifications, features, and functionalities of these devices. It would be great if you could provide details on different sizes available, as well as any customization options for colors, primarily looking at black and gray. Additionally, I would appreciate information regarding the pricing structure, minimum order quantities, and lead times for delivery. If there are any available user manuals or demo videos, that would be very helpful in understanding how these products operate. Looking forward to your prompt response!
