This is a well made toy and does target the prostate as advertised. It is comfortable to wear and more or less does what it's designed to do. On the whole, I am not sure these devices live up to the hype and implied promises of mind blowing "hands-free orgams" or the elusive "super-O", but they do add some intensity to orgasm, just not as much as other toys I have used. This is better than the aneros SGX, but nowhere near as fun as the Get a grip was for me, so I give it about a 3.7

The Janus Anti Shock High Performance Prostate Massager by Zini is a great little toy designed for male p-spot stimulation. Because of its small size, it is ideal for those are curious or new to anal play. The more experienced users may appreciate its use for warm up or extended play.

I feel a bit bad comparing the Janus to Aneros' products, but I feel that it's so obviously derivative it's hard to avoid. I have to say that I liked the material better, and certain elements of the construction were nicer. It did not manage to reach my prostate, but I that may be remedied by getting a bigger size.

This new line of prostate massagers from Zini is a great way to explore the world of P-spot play. Zini gives you a hard plastic structure/base and the insertable section is covered with soft, plush silicone. The angle coupled with the raised texture come together to make one good looking toy and an even better P-spot massager. Look out Aneros!

The Zini JANUS Anti-Shock P-spot massager is a wonderful way for a beginner to start their journey into the world of anal play. For the more advanced user one of the larger sizes may be advised, but this little guy still has a few tricks up his sleeve that may surprise you.

This toy's small size makes it deceptive. It's very stimulating yet super easy to insert with virtually no warm-up required for all, except the most uptight anus. More experienced users will enjoy the comfort of this toy for long term wear and the amount of stimulation it provides for its small size. Overall a well deserving five stars.
