I ordered 5 of these. One for my husband, one for myself, one for my dad and one for my mom. I have an extra I am putting in the car. I drive around 600 miles a week for work. There are no rolling motors but I am a bit of a baby when those are involved. I think they hurt too much. The vibrations can be set to 3 different speeds, though, so if you want deeper penetration you can crank them up! There are 4 different sections that are controlled either individually or with one of the 4 programs. The speed in the programs can be adjusted as well. Each section can be turned off or on independently. The heat option only heats in the lower back and also works independently. There is an adapter that goes to wall or car. If you are using it in your car, it will add some height and thickness to the back and seat. Adjusting your seat and steering wheel might be necessary. I have mine on my desk chair and use the 2nd program on medium speed with heat on. So far I am loving it! ..More
