Klein's design was a significant advancement over previous models. Early electric wheelchairs were often bulky, cumbersome, and limited in functionality. They typically featured large, heavy batteries and required considerable effort to operate. In contrast, Klein's electric wheelchair was more compact and user-friendly, incorporating a joystick control that provided seamless maneuverability. Users could easily steer, stop, and navigate tight spaces with minimal effort, making it a revolutionary tool for mobility.

However, accessibility to medical equipment is just as important as its innovation. Med Shop focuses on ensuring that healthcare facilities—regardless of size—have the equipment they need. This commitment extends to not just supplying hospitals and clinics, but also to individual patients who may require home health care equipment. This includes items such as wheelchairs, oxygen tanks, and advanced home monitoring devices that empower patients to manage their health independently.
