From the maker of Meiki Maria Ozawa comes this mid-level dual layer onahole series called Zettyo-Synergy. This dual layer system called "Bipolar System" uses two different material to produce an unique feeling. The outer material of Zettyo-Synergy is firm but not hard providing a tight feeling during use. The inside wall are lined with small nubs and large ribs made with another material to provide a stronger/softer stimulation depending on model. The large inner chamber along with the small entrance allows for great vacuum feeling simply by squeezing air out when inserting. Zettyo Synergy Yuuna has a series of large ribs and long and short nubs. A choke point near the end creates a strong stimulation. Yuuna has a larger inner chamber than Arisu allowing for a stronger vacuum sensation. Yuuna's Bipolar system has a firmer inner layer compared to Arisu. *Use only water-based lotion or lube with this product.

This unit is ok but not sensational. I wasn't able to climax the first time I used it - the inner layer is much firmer than it needs to be, so if you're used to the softer toys this will take some getting used to. The entry is very small, so if you have a lot of girth you'll tear it slightly at that point. One more note: since the "main" chamber is wider than the front and back, this thing wants a LOT of lube. Bottom line, though, as far as I'm concerned is that this is a good toy to use at the beginning, if you don't want to climax, but you'll need to switch to something else before going numb.
