Gave this to a friend to leave in his RV to use to rotate scissor stabilizer corner jacks up and down. Enough performance for such an effort, but poor battery life; he said that would hold them up, and at the end of their trek or when they got together to move on to the next campground, he would unload before turning back the four jacks. Then he has to pull out the handle to finish the job. Considering it's about five seconds per corner, that's pretty poor battery life.
