According to the product, there are 8 modes, which increase the intensity. Be aware that in each mode you have 19 levels, but mn. . . To be honest, those 19 levels are just visual because from what I saw and tried, I only feel the level increase to level 5, hence the rest of the levels are the same as 5, as for the delivery, it arrived between the estimated days on the second day. I liked the product, I use it both to relax and to do joke, I recommend it, I just didn't like that aspect of the 19 levels, I would prefer it to just be left in 5.
