A:Answer No way for me to compare but I will say that the intensity level is 1 through 5 and is a very noticeable difference, and with 2D I think it is a fixed amount. The 3D varies intensity by just moving the rollers out more, closer to your body. Some sensitive areas of my back, 1 is almost too strong while I can handle a 5 in other areas. You can use Manual mode and set it to do a spot massage if you like, and crank the intensity to really work that single area. Or instead of spot you can let it do a slightly wider range, or of course a big range like upper or lower or neck/shoulders or butt.
