StairBusters.com has been wonderful to work with. I have used the company twice now in two different houses; my son-in-law's house and my own home. At ninety-four years old, I prefer to stay in my own home for as long as I can. StairBusters.com has enabled me to do that. I liked their product so much that I had them install two chair lifts in my home; one going upstairs and a second chair lift going down to the basement. They are getting a lot of use too. In fact, today is my laundry day and I have been using the chair lift all day long. I can get down to the freezer on my own and everything. Andy, the technician who installed the chair lifts for me, was very polite and helpful. He was very careful in making sure that I understood everything there was to know about operating the chair lift. He even took the time to watch me run it on my own before he left. Believe me, I have no complaints about StairBusters.com. I highly recommend using them. I have already been referring them to people I know.
