We worked with Doug from Minnesota Amramp. My wife needs a mobility scooter to move around. We had an aluminum ramp out the back steps and it worked but it was a fairly steep incline and had no side rails. It was like a thrill ride going down and she needed to be pushed to get up. The Amramp is a bit longer, more sturdy, has side rails, is more attractive, and it's a smooth easy ride up and down. It's not the cheapest option, but the quality is outstanding and it exceeded the results we were hoping for. The entire process was easy, they were responsive and punctual, and it was installed as soon as the snowpile on the deck melted away. Extremely satisfied with the product and the service.
