Yours is one of the most well deserved downvotes. Dude got paralyzed, literally cannot walk or stand anymore, received the exoskeleton (which was paid for in full by a fundraiser back in 2015) and the company simply decided "nah, we don't touch anything older than 5 years", knowing full well that this is NOT a disposable device and that Michael would need it for the rest of his life.
Keep in mind Lifewalk, the company behind the exoskeleton, didn't even try to come up with a public bullshit reason to deny maintenance to a device that they knew full well would be used for the rest of the person's life, or upsell a newer model.
