I purchased one of these last December before a 1500 mile road trip. It really helped me alot with the long sitting times and I could actually get out of the car and walk right away...instead of slowly getting out and getting going. Back surgery 5 or 6 years ago and still have trouble with it when I sit for long times. It takes some getting used to, but it works. I paid less than $30.00 for it at LQS and not on sale. I think you will like it.
