Quite the Handful!It is hard to justify the $30 price tag on this toy, since it is so awkward in size and limited in use. It might be okay if you're just looking for something to roll over your body, but I would recommend finding a better quality massage toy for that.
It doesn't seem to be very useful for direct clitoral stimulation because of how large and awkward it is. After some experimentation, I did discover that the size makes it excellent for using on the sensitive bits of men. Balls tend to be too sensitive for extreme vibration, so the low vibration and wide surface area makes it great for rolling around on the scrotum and perineum. My partner, who has never used vibrators before, has become much more interested in trying new things since we tried using the pleasure ball on him.
In terms of the design, I would prefer that it was entirely TPR, as the plastic feels cheap and takes away from the aesthetic quality of the toy. Fortunately, since it isn't silicone, you can use silicone-based lube or water-based. The webpage states that it is waterproof, but I haven't noticed any kind of seal to keep water out, and am hesitant to try using it in the shower or elsewhere.
I think the Pleasure Ball might be a good option for people who are extremely sensitive and have a hard time with direct clitoral stimulation. Alternately, for anyone who is into sensation play, rolling it over the body might be very exciting.
As a free toy with purchase, I am pleased with it. However, the $30 price tag is a bit much for me to justify normally. I can use many other vibrators for my partner's man parts that are more versatile. This is just my opinion though. I could easily see where others who are sensitive or new to vibrating toys would be able to use this to explore without feeling threatened by over-stimulation, or being constrained to using the toy in only one way.
