Easy to assemble and heavy duty. Wife uses a power wheel chair and it supports her and wheel chair without any movement. I can recomend this ramp. However, for a 3" rise it is a bit of a steep incline.
I am pleased with the ramps. They are serving the purpose intended to the doorway entrance. They are also strong and steady. My mother has easy access in and out of the doorway with her walker
