This device works very well! I've read a lot of RV posts where people carry cordless drills to lower the stabilizer legs on their RVs. Perhaps larger RVs require more physical exertion, but I find it to be a quick and easy job that doesn't require battery power (electric charging) or heavy tools that I don't usually take with me when camping. I use it on a retractable A-frame RV. A few seconds on each side and you're done.
