We heard about StairBusters.com from friends. They were great to work with. The representative brought out a lot of books with different models in it and took his time to explain thoroughly the different units and which ones would work the best for us. When we were ready to make the purchase we felt confident in our decision because we were well informed. The installers were wonderful to work with. They were very kind and generous. They arrived on time and got to work right away. They took the time to answer all of our questions. They didn't make us feel rushed or pressured. They were respectful of our home and courteous. They were very knowledgeable. Once it was set up they did the test run and explained features of the unit and maintenance tips. They were very professional and it was a pleasure working with them. We would highly recommend using StairBusters.com!
