I needed a small ramp that could work to get my mom's transport chair out of the apartment and over a six inch step to get onto our terrace. These work great. They are small enough that they can be stored easily outside (we needed the smallest size) when not in use and are fairly easy to set up. You definitely need to have a bit of strength to move them around--they're heavy! But I wouldn't want something flimsy for this kind of thing. The materials are very durable and high quality with anti-slip material on the ramp and raised sides to avoid sliding off. As a nice bonus they also come with work gloves that make carrying and set up even easier.
