I had high hopes for this because of the reviews I'd read. As someone that can pretty much only get off from these types of vibrators because of sexual disfunction I've tried a lot of suction/air pulse vibrators and this one is absolutely the worst I've owned. The highest setting is not that high, and the intensity/rumblieness/whatever you want to call it is negligible. I'm super disappointed because of the price point. Absolutely can't finish with it at all, just kind of numbs everything out.
It's good quality though I guess.
Sonic waves are a great thing.
I do not like to insert toys and this is a great solution. I read a lot about the product, the first version, and decided to buy this improved version. I put it very, very close to my skin and I can feel waves kitting me and going deep into the tissue. A wonderful sensation. A bit strange in the beginning, I must say. However, a month later, it is one of the most important items in my household. A great new friend. Gentle when I want it to be, strong as well. Lots of pleasure from a well designed toy.
