The size and shape of this toy are great for beginner or intermediate prostate play. While the basic bullet vibe included with it is alright, I highly reccomend upgrading to another vibe if you can, as this toy is great with the many options out there. Personally, I use the Sensuelle Joie vibe, which can be found affordably on amazon. It's a very powerful vibe with 15 different functions and usb charging, which makes a phenomenal pairing with this toy.
Now, while I really like this toy for the most part, there are two issues I've had with it. First, it seems to dry up rather quickly. I typically use only water based lube, which doesn't last all too long, but this toy seems to just eat it up. In addition, this toy is not contoured for much staying power. As such, there are a few positions where it will either start to slip or completely fall out. This can be very upsetting in the moment and as of yet I haven't found a good fix. In any case, it's still a good toy, but just has a few important notes.
