This is the first time I've ever had this. I just recieved my new wheelchair and when I'm not in it, one of the front casters doesn't touch the ground. And it's pissing me off. It's probably only a millimeter off the ground. This is the first time it's happened and i'm not sure if I need to take the chair back to the DME or just suck it up. This is the second RGK Wheelchair I've had in 20 years, Yes the other one lasted that long. and the first since they were bought out by Sunrise.
