Good stimulation, the orbs are very noticeable.
Design made cleaning very convenient (biggest advantage) but it's still hard to dry because the inner texture is so complicated. Also the frame only clicks into place without anything to secure it properly, so it can pop open while using it.
However it seems to have durability problems. The soft interior tends to bulge against the hard frame when using it, which makes it feel flimsy. I found a tear on the inside within a month of using it. With problems like this, I don't think it's worth the full price.
