I received the RO-120mm bullet as a gift, and it can now be counted as possibly the best gift I've ever gotten.

When I hear of "bullet" vibes, I conjure the image of the little egg-like vibes I'm used to hearing about. The 120 is definitely more than that, and packs more within its larger confines as well. It has five settings, from a medium to strong buzz, and other pulsating levels that are easily cycled through with the top button. It's simple to click on, and hold down to turn on and off. At its highest setting, it is QUITE strong and the width of it gives it the perfect size and shape to cover the entirety of the clitoral area.

Though it can be used for shallow penetration, it's a bit too solid to do so comfortably. The silver coating is shiny and smooth, but unfortunately it tends to wear with use. I've had mine little over a year and the metal surface is all but completely rubbed off to reveal the garish yellow plastic underneath.

My only other complaint besides the wearing, is that it does tend to eat up its AA batteries. It's still functional when the juice is getting low, but definitely nowhere near as strong as with a fresh pair. The good news is that even at its most powerful, it is relatively quiet.

Yet, putting aside those two features, I would say that this is my favorite clitoral vibe out of all the ones I've tried. I've used it in the bedroom, the bathroom (waterproof!) and just about anywhere else sex can be had. It is my go-to toy for solo play and couple's play. I think of it as Old Faithful because it always comes through for me, and my intense orgasms can attest to this.

It may take a second to get used to holding it, but once you find it, it will come in handy in a variety of ways. I have used this toy alone as well as with a partner. I can say I have had amazing orgasms during sex by using the 120 bullet in missionary and doggystyle positions. It's big enough to get the job done, but small enough not to get in the way of your coupled passion.
