I was very intrigued by this vibe when I initially saw the design. My girlfriend was curious as well. The material of the vibe is very soft, like the usual silky feeling of many higher end vibrators. The vibrator is waterproof, and fits easily in the palm of your hand. There is one button to cycle through the vibration patterns, and by holding the button you can turn it off. Finally, there is a small charging port on the back which is discreet and remains waterproof.
Actually using the toy was a bit different than expected. Most vibrators we have used transfer the vibrations directly to a stimulating tip or a broader point. This toy has two rubber protrusions with ridges on the inside. We tried using them to stimulate her by surrounding her clit first but this didn't do much for her. We had to experiment a bit to find what worked best.
Ultimately we found that it was easier for me to stimulate her with the toy, than for her to stimulate herself. When she was using the toy she felt like she couldn't please herself as she wanted and ultimately got frustrated. When I used it on the other hand I found it to be a bit more enticing than using a simple dildo or bullet. I was able to play with how I was stimulating her, and tried it in a variety of areas including her nipples.
After a few times trying the toy out, she wasn't too enthused about using it in lieu of her other vibrators. I think it is worth noting though that this is largely due to other toys getting her off quickly, so someone who is looking for a toy that will keep them going for a longer haul may find that this toy suits their needs more.
Ultimately, I see myself breaking out this toy again to help tease her before bringing out the stronger vibes to finish the job.
