My wife had ankle surgery and was on a knee scooter for four months. We needed a ramp as our house is three feet above grade, and Amramp arrived in less than a week to install. Took less than a half day and we had a ramp that was invaluable to her recovery. When she was walking again and comfortable with stairs, Amramp came back to dismantle the ramp. Only took them a couple of hours. Also billing was reasonable and easy to pay. Thank you Amramp!
