Peace, mercy, and blessings of God be upon you. I have the Hypershell X device, an AI-powered assistant for walking and climbing stairs. It runs on batteries and comes with two batteries. It helps the elderly and people with leg and knee problems. I bought it for my mother, but she didn't like wearing the device. I don't need the device. It cost me 5000 SAR when I bought it. Now it's 3000 SAR. A video explaining the device. Whoever is interested can search for the device name on YouTube to see more of its features. I am located in Al-Ahsa.
