We bought a used chairlift from StairBusters.com and it took several service calls to get it working properly. It was not a good experience at first. They ended up replacing nearly everything on it and now it is working fine. One time when we needed to get it serviced, they did not have any techs available and that caused us some problems. But another time, one of their techs was excellent. I mean he was exceptional. He really helped us out and he turned the chair to where my father could get in and out of it easier. He was very nice and very helpful. Overall, my takeaway from this is that I will never buy another used chairlift. This one is working fine now, but it took some time to get it to that point.
