The Harmony Wireless Wonder by Doc Johnson is wireless vibrating bullet in the theme of Yin and Yang. The packaging is porn star free, covered instead by subtle colors, Eastern styled fonts, and a Yin-Yang on each side. The Harmony comes in two colors—black (Yin) and white (Yang). The Yin and Yang of color choices also works as the balance of power when handing off the remote to someone else to control your pleasure.

Made of ABS plastic, this product is phthalates-free, compatible with all lubes, but cannot be sterilized, so use condoms if sharing.

I found the bullet to be larger than I had expected (3.5” long) and I was a little worried about how comfortable it would be. It is a tapered, teardrop shape, which was very easy to insert, with a two inch looped retrieval cord on the end. The cord is also made of plastic and reminded me of gimp. (Even with a cord, bullets are not for bums, so please keep anal play to anal approved toys for safety’s sake.) There is a subtle seam where the bullet unscrews to insert the batteries that can be felt with fingers, but not internally. Once inserted, I found the bullet to be very comfortable, even while wearing it for extended periods of time. If I worked my PC muscles with this toy in, I could feel it nudging my g-spot. The only discomfort I felt was if the bullet was not fully inserted and the small hard plastic nub that protrudes to hold the cord was pressed against my vaginal opening. But that could be adjusted and fixed.

The remote is smaller than the bullet and could likely be concealed completely in larger hands. It also has a cord with a lobster-claw style clip on the end so if you wanted you could clip this thing on your keychain. We found the clip to be very convenient; clipping the remote to the retrieval cord on the bullet makes sure they are not separated while in storage. The remote has two buttons: an On/Off button and a button that changes the settings. The inclusion of a quick shut off button is great so you don’t have to scan through all the functions to turn the toy off. There is also a green LED that lights up whenever you push a button, but does not stay on.

On to the action. The Harmony runs on 3 N type batteries in the bullet and one 12V battery in the remote. These are some funky batteries—luckily they are included. There was no booklet to explain how to insert the batteries but you really don’t need one. There are markers on each piece of the Harmony for battery type and direction so installation was a breeze.

The vibration is a middle frequency: neither high and buzzy nor low and thrumming. With the vibrations concentrated near the tip, it is great for external use, and internally the vibes could be felt in my g-spot, the sensitive entrance to my vagina, and lightly in my clit.

We found that the control of this toy was not exactly reliable. The remote would work through doors and through walls and many feet away—sometimes. Sometimes it would only work a few feet away. Sometimes only a few inches. Sometimes it took direction right away, and other times we had to push the button several times to get the bullet to respond at all, even when not inserted.

The other problem we had with the control was that if the person holding the remote is not the one using the bullet, it is hard to tell what setting the bullet is really on. If the bullet could be trusted to switch settings and turn on/off on just one push then you could count, but we’ve found that we can’t trust it to do that. This does speak to another great plus for this toy: it is so QUIET that even laying next to me, my partner could barely tell if it was on and certainly couldn’t tell what setting it was on. For this reason, I’d say that as long as you weren’t in a completely silent room, you could definitely take this out in public.

Clean up is super easy with this one. The bullet is waterproof and rinses off easy with mild soap or toy cleaner. I’ve had no trouble with any leaking in the toy. The remote is not waterproof, however.

We had an absolutely great time with this toy, but after only two uses the batteries are already dying; the bullet now only has one setting. But I know it’s a good toy because while I’m not sure where to find N or 12V batteries, I am determined to find them for this one.

Having this inserted and handing the controls over to my partner was a great thrill. It was comfortable during arousal, didn’t shift or pop out during climax, and was still comfortable afterward. I was not able to climax with the internal vibration alone, but it got me soaking wet while I my partner teased me, and when she finally did touch me, I practically burst.

There are so many great ways you can use this toy: When used for external stimulation, the remote holder is in a position to really tease the person with the bullet. It can be worn around the house for a nice surprise jump when the person with the remote wants. If you’re feeling kinky, the Dom/me can use the remote as a reward system for the wearer when she does sometime s/he likes. My personal favorite was wearing the bullet internally along with a strap-on while I fucked my partner—it added great stimulation for me, and my partner loved watching me shudder when she turned it on and off.

I usually list the functions of toys like this, but as the batteries are pretty much dead and I haven’t been able to find new ones, this is what I can remember and I’ll be sure to include them in a follow up when I get replacement batteries. The first three are straight vibration with a low, a medium, then high. The fourth was very unique and my absolute favorite—a low fluttering that builds to a strong pulsing before starting over. The last three are varieties of pulsing functions that I don’t remember exactly.

I haven’t yet found a toy with strange batteries that I was willing to go out of my way to find replacements for, but this is definitely one of them. If the Harmony didn’t eat through batteries and the controller worked accurately, I would have easily given this one a 5/5.
