walking pad (Gaithersburg/Flower Hill)

Hi!! I’m looking for an electric walking pad to help me get my steps in, and alleviate back pain, while I’m working, watching movies, reading, volunteering digitally, taking classes, etc. I stand at work but my back is angry if I’m standing still for too long; a walking pad would make a huge difference. Photo attached is an example. Thank you so very much in advance 💙💙
