This is the worst company to buy mobility equipment from! They don't respond quicky (or at all) even for a paraplegic 8 year old child. We purchased the last chair for my grandson fall of 2021 & rec'd it Jan. '22. It was a total "lemon", parts falling off quickly and often, from every part of the chair. It was difficult to get the repairman out, although I will say to his defense, NSM had 1 guy to cover half of NYS! When a repairman did come to fix the chair, he was good and knowledgeable, but overworked. Main office avoids calls, never calling back by 4PM the same day as their recording states. If you do get a live person, they always have to "check" and call you back which mostly doesn't happen. I had to eventually speak to the manufacturer of the chair in CA who was able to replace it months later although, Sales Rep for NSM never offered that option, nor did he want to help with making that happen. New chair rec'd Dec.22. It was a very long & hard year for a kid who can't walk & relies on his chair. He missed school often and couldn't ride the bus many days as parts flew off randomly. He was often afraid when the back slipped or his brake handles flew off. Sales are priority for NSM and not customer service. The 1st wheelchair my grandson had almost 5 yrs. from another vendor with no problems except regular maintenance. They responded quickly when called. I should not have let myself be talked into NSM & will not use them in the future. This company needs to hire more repair people for all areas that they sell equipment to and focus more on the needs of the folks who buy. For most it's far more important to have their equipment working than to have a smooth talking salesman. Sad to have to write this review. read more
