StairBusters.com was a great company to use to install my new stairlift. They did a really good job. They demonstrated how everything worked. They told what to do and what not to do. They also told me that it has a battery back-up that lasts for two hours if the power goes out. The installers were very thorough! I had to wait until I got financing approval from the government before finalizing the installation date, but they waited and worked around my schedule. If I ever needed anything like this again, I'd call StairBusters.com right back. Five stars!
