This toy looks nice enough, but my first impression was that it was on the small side (it's only 3.25 inches long!). I have been looking for a good g-spot vibrator, but for me, this wasn't it. I'm used to much larger and more powerful toys, and since this toy was so small, I couldn't get it to stay on my g-spot, especially without it turning off. I only used it on myself a few times, and it's just *meh* to me, so I unfortunately do not have as lengthy as a review as I would like to! My girlfriend and I used it recently and she really seemed to like it. It was her first time being penetrated by anything other than fingers so it was nice to see her reaction. This toy really seems geared toward people who aren't very experienced with toys or would like something small to travel with.

The Tantric Zen is also relatively quiet. It couldn't be heard through a door, but it can definitely be heard if you're in the same room with it. Also, the on/off button lights up which is nice/useful if you're using it on a partner in the dark.

The toy itself is silicone, so don't use silicone based lube with it! It is also waterproof. I haven't used it in a shower or anything yet, but the waterproof feature is nice for cleaning purposes if nothing else.

Girlfriend's review-
I recently used the Tantric 10 Function Zen Massager and I thought that it was a fairly good product. It works great for penetration or for clitoral stimulation. The only problem that I found with it is that the button placement is terrible and should but put somewhere else. It wasn't hard to accidentally turn it off while using it. But, overall I liked the product and would use it again.

I used this on my girlfriend and the thing randomly stopped and would not turn back on. The next day, she opened it and apparently the battery was somehow loose. There's no paper liner to hold the battery in place like some toys I've had in the past- perhaps it's because it's waterproof? Or maybe I accidentally threw it away... Either way, it was annoying for it to turn off in the middle of use!
