Hangs on Like a Koa-la

If you enjoy cock rings for the direct clitoral stimulation they provide, this one will disappoint. If you are interested in turning your partner's penis into a vibrating one, this will impress. The design of this ring makes it possible for you to use it for broad or pinpoint clitoral stimulation, either solo or with a partner, when you aren't having sex, which is not something a lot of other cock rings do well. It's a unique toy that isn't likely to be like anything else in your toy box.

extremely useful review


This little guy is one interesting animal. When I saw it, I knew I had to have it. I know the other reviews are less than stellar. I know that it seems like an odd design. But, you have to admire the moxie it takes to produce a cock ring that isn't a stretchy ring that goes around a cock. At least, I admire it. So I knew I needed to try it.

Whether it looks like the standard in that category or not, the Koa is first and foremost a cock ring. It can be used on a penis or a dildo. You can position it so that the bulb shaped vibrator attached to the ring faces up, down, left or right. The level of direct stimulation changes, depending on which placement you choose. No matter which direction you point the bulb, the penis or dildo you attach the Koa to will vibrate from base to tip. I'm not a fan of pinpoint clitoral stimulation, so the broad vibrations the Koa offers appeal to me. If you're a fan of cock rings, and the vibrations causing the vibrating penis effect, you will enjoy the sensations the Koa delivers.

Unlike stretchy cock rings, which are more or less one size fits all, the clip on the Koa may be uncomfortable for those men who are well endowed. The Koa isn't going to cause a whole lot of constriction, so if you like to use a cock ring to help maintain an erection, this isn't likely to work for that.

The Koa can be used as a stand alone vibrator as well. The handle is convenient when you use it for clitoral stimulation. It has a great shape for clitoral play, allowing for broad or pinpoint stimulation depending on your preference. I wouldn't recommend it as a great option for internal stimulation unless you enjoy very short toys. It can be used to tease the vaginal opening, and can be inserted a bit, but it isn't going to reach your g-spot.

Although I suppose the clip would act as a flared base, I wouldn't suggest the Koa for use as an anal plug. It could be used to tease the anal opening, and perhaps for a bit of insertion play, if you were careful to avoid being poked by the clip. I would also avoid inserting it up to the seam where the clip screws onto the bulb, as the seam will collect bacteria and fluids. Remember to thoroughly clean the toy after anal play before using it anywhere near your vaginal area.

Material / Texture

There are two basic materials to the Koa: silicone and plastic.

The blub of the Koa is made of silicone, which is non-porous, phthalates-free, latex free, and hypo-allergenic. It has a smooth, velvety feel with little to no drag. The silicone is covering a hard plastic core, so there is no squish to it.

The hook/clip of the Koa is made of hard plastic. It is slim, so is has some give and bend. There is a seam which runs the length of the clip, but it cannot be felt during use.

There is no smell or taste to any portion of the Koa. I have tried a fair amount of cock rings made of a stretchy sticky material, and this one provides a refreshing change from those. It won't grab hair or feel stick to the touch.
    • No odor
    • Not porous at all

Shape / Design / Size / Fit

What I noticed first is that there is no way to attach this ring to a penis and have it lay directly over your clitoris while you're having sex. This seems odd for a cock ring, most of which have the same basic design that does exactly that. What this ring does, is cause the penis it's around to vibrate, turning your partner's penis into a vibrating penis.

The ring itself has enough give to accommodate a wide range of penis sizes, but I fear that although it will attach to a larger penis, it will probably not remain secure during sex. It is easy to put on and take off, and my husband reported that although it was an odd feeling having it clipped there, it wasn't uncomfortable. I didn't have an issue with it moving or falling off during use. It is impossible to use this clip over both the testicles and shaft, as it doesn't have enough clip to reach around both. It simply isn't designed for that use, so stick with using it on your partner's penis.

The total length of the ring from loop to tip is 4". The width of the bulb is 1". The clip itself, at rest, measures 1" in diameter, but the arm of the clip can be pulled open until the clip arm is flat. I have pulled and bent the clip arm flat many times and it shows no sign of weakness or stress, so I feel like it will last through many uses, even on a larger user.
    • Only fits on penis shaft
    • Will fit most men

Functions / Performance / Controls

On the bulb of the Koa, there is an imprinted word "picobong". Within the "p" is a "-" button, and within the "b" is a "+" button. These two buttons are the only controls. Pressing the "+" button activates the vibrations. Subsequent presses to the "+" button increase the intensity. There are twelve vibration modes, the first of which is the steady vibration setting. Pressing and holding the "+" button for longer than two seconds, and then releasing it, cycles you through the vibration patterns.

The 12 modes are:

1-- steady vibrations of varied intensities, depending on how long you hold down the "+" button
2-- alternating periods of nothing and vibrations
3-- pulse
4-- faster pulsation
5-- very speedy pulsation
6-- roller coaster
7-- speedier roller coaster
8-- ascending and descending vibration cycle
9-- rolling wave of vibrations
10-- pattern with an ascending vibration and then three pulses
11-- pattern with an ascending vibration and then five pulses
12-- random patterns

Pressing the holding the "-" button will turn the toy off. The toy is all but silent, with no distracting noise on even the highest setting. Aside from the sensation it provides, it's easy to forget it's even there.

I would say that at maximum intensity it reaches 3 vrooms, but with a nice deep rumble. The vibrations are centered in the bulb, but can be felt ever so slightly in the clip. The buttons themselves can be difficult to press, but once you set the pattern or intensity you desire and put it on a penis or a dildo, you don't have to worry about it changing or being accidentally hit while in use. The Koa takes one AAA battery. The bulb of the Koa unscrews from the clip, the battery is inserted and the clip is screwed back on.

The Koa is waterproof, and has survived the handful of times I have submerged it. The vibrations transfer well through a dildo, even during underwater use.

One thing to note:

The seam where the bulb screws to the clip does allow for fluid collection. After using the Koa, be sure you unscrew the clip and clean it thoroughly. Also, check the area before use to make sure it's clean. You cannot feel the seam while in use, and it doesn't allow for fluids to get into the battery compartment, but it is something to be aware of.
    • Comfortable during use
    • Easy to use

Care and Maintenance

Cleaning the Koa is easy. Because it is waterproof, while the bulb and clip are screwed together you can run it under running water and use mild soap to clean it. Another option for cleaning would be to use your favorite toy cleaner. The motor in the Koa prevents it from being able to be boiled for sterilization, but you could wipe the toy down with a 10% bleach solution should you wish to sterilize it.

As the bulb is silicone, you will want to avoid using silicone lubes with the Koa. Any water-based lube can be used safely. Also, take care to avoid storing the Koa touching any other silicone toys to avoid damaging them. It can be stored in a plastic bag to keep it safe.
    • Difficult to store
    • Easy to store


The Koa comes in a cardboard box with a clear plastic window in the front which displays the toy. The color of the box matches the color of the toy, so it will vary depending on the color you chose. There is an instruction booklet included which details the use of the Koa, and explains the controls of the toy. I wouldn't call the package discreet, or particularly good for storage. It is minimalistic and practical, which isn't a negative point, as far as I'm concerned.

Personal comments

The Koa, and every Picobong item, comes with a small black six sided die. Each side of the die has a picture of one of the Picobong toys. If you visit the Picobong website, it tells you to use the die to play a game which decides which toy in the line you'll use that night. This seems a bit silly, since you would need to have each toy, but you could reassign the pictures to what they stimulate and make your own game.


I said it before, and I'll say it again. I got this toy because it was just so odd that I needed to see how it worked. I was pleasantly surprised. The vibrations have a nice rumble, the toy is nearly silent and I can use it lots of ways.

When my husband and I used this as a cock ring, we had success with it staying put. We tried it facing several directions, and didn't find one that was unpleasant. The vibrations were felt all the way to the tip of his penis and were enjoyable for both of us. True, it didn't stimulate my clitoris unless he held himself against it, but it really isn't designed to.

As a discreet clitoral massage toy, it feel amazing. The rumble is enough to get the job done, and I think that most users will be satisfied with the amount of power it has. I find that if I loop my fingers through the clip, I can push down on the bulb from the opposite side to apply pressure along with the vibrations. I do feel the vibrations in my hand when I use it that way, but it isn't bothersome enough to annoy.

I have tried to use it for internal vaginal teasing, and I enjoyed it that way as well. Obviously, it will never be the vibe I reach for when I want a feeling of fullness or deep thrusting, but it feels great parked there while I use my hands for clitoral play.

In addition to clitoral stimulation, and it's primary purpose as a cock ring, the Koa is great for teasing other areas as well. I like teasing my nipples with it, but no matter where you enjoy teasing it's comfortable to hold and manipulate.
Follow-up commentary
Although it isn't my favorite, it still works just as well as the day it came in the mail. It is a great choice if you need one toy that can work for several functions. Read the cons of my review carefully, but if your guy is average sized, this makes a great addition to your play.
