The device is as described. Unfortunately, you can not combine with the heat function of vibration without running the fan. The bladder function "Whirl" is quite noisy but the pure vibration mode, the device does not heat up the water. I think that's a great pity! In addition, the heat is quite irregular resulting in that you look at some feet from overheating but then again waits for the heating starts. For the price you should probably not expect all too much, though unfortunate, since certain functions require only a small adjustment of the electrical system. Perhaps the manufacturers have not been tested on the product itself (?). Well, in the end everything luxury problems ....
