I've used these in the past that just have 1 or 2 of these functions but it's the first time I've seen one with vibration, rotation and suction. The three together really provide an amazing sensation. And each of those functions have different levels you can independently set so there are so many combinations! Adjust based on how long you want to go for and change it up in the middle. It's soft and it doesn't take long to have some warmth to it. It's waterproof, which gives you options for where to use it. It cleans up easy. It even comes with a bottle of lube. As long as your ok with something that has some weight to it this is something that every guy should enjoy. Don't forget to charge it when you're done because you'll want it to be ready again when you are. If you're just going to get one of this type of device, this is the one to get because of all the options.
