I was cleaning up my garage a couple days ago, actually I was looking for stuff I have not been able to find for awhile. I found this hidden behind some other stuff. I pulled it out and decided to use it today. After about 30 minutes of getting up and down and rolling around, I just put it back where it was hidden before. I think I will just stick to a blanket and shimmy in and out from under the car. It's alot easier this way. It's definitely not easy getting older. how about you seasoned guys, you still using one?
