I was quite pleased with how the work from StairBusters.com went. We went to them to have them install an electric chair to go up the stairs as they were getting hard for us to get up. The people that came out were very helpful, and did the install very quickly and without any issue, it was completed much quicker than I thought. Since the install we haven't had any issues, the product works very well and we are very pleased. I highly recommend their services!
