The PicoBong Koa by Lelo is listed as a vibrating penis ring, but I didn't use it for its intended purpose, but instead I used it as a bullet. Bullets can be used on any erogenous zone that likes to be stimulated such as the clitoris, nipples, vagina, labia, mans penis or testicles. They can also be used for very shallow vaginal insertion.

It can be used alone or with a partner. Alone, you could use it by itself or in conjunction with a dildo or insertable vibrator. I really like the idea that it can give vibrations to dildos or other vibrators. With a partner, they can control the bullet for you to tease and please you.

The Koa should not be used anally because it does not have a flared base and is quite small so it could potentially get lost if used anally.

It is considered to be waterproof so it can be used in any water setting that you wish such as the tub, shower, hot tub, or swimming pool.

As a cock ring, this is not a full ring and I do not see how it would restrict blood flow allowing a male to have a longer, harder, firmer, erection and stronger orgasm. Most rings are fully circular and have the ability to do so, but this one is just a clip so I feel most males are not going to feel fully constricted.

The toy is made out of a combination of silicone and ABS plastic. The bullet area is made of high quality velvety silicone and the clip is made out of sturdy plastic. Silicone rates a 10 on the safety scale and is considered durable and easy to clean. Plastic rates an 8 on the safety scale. Both are considered to be safe for the body and are food grade materials, hypoallergenic, latex free, non-porous, and phthalates free.

The Koa is hard, smooth, soft, and offers no flexibility at all. The majority of the Koa is a dull, matte black whereas the clip is a shiny black. The portion that is matte is softer than the section that is glossy. The bullet section does not offer any texture at all, so if you are one that loves toys with texture then this toy is not for you. The clip is somewhat flexible, but not enough to fit over some of my thicker toys and wouldn't shrink to fit on some of my thinner toys. There is a small visible vertical seam that runs the length of the Koa, but it cannot be felt. The bullet also has raised letters of the name PicoBong written sideways along the top of the bullet, but it can't be felt during insertion. Overall, it is best suited for those that enjoy smooth, hard toys with no distinguishing texture.

The silicone has a lot of drag to it so unless you produce a lot of natural lubrication, lubricant is advised to be used.

There is no smell or taste to it.

The Koa comes in three colors to choose from pink, black, and purple. I have the black and again it is a matte black with a shiny gloss to the clip.

The Koa looks like a bullet with a tail at the end that is supposed to slip around a males penis. In that regard, I was not able to test it out on a human partner, but I did test it out on various toys. When using it with a toy, the Koa would slip on sideways and would not sit in the proper direction to aid in clitoral stimulation. It is very easy to slip on and off the toys, but you just can't get it to align to your body to aid in stimulation in the places you want it.



On a toy, if it's thinner the Koa won't fit on there, and if it's thicker it won't fit on there properly either. I'm going to assume that would be the same case for a male penis. If the penis was thinner in girth, the ring would have excess around it and wouldn't constrict the blood flow like cock rings are designed to do. If the males penis was thicker, the clip may pinch into his skin and cause discomfort. Again, I don't know this for a fact, but this is what I experienced with my toys.



The clip gets in the way when you try to use it as a bullet for shallow vaginal insertion no matter which way you turn it. The best way to hold it as a bullet is by having the clip in your hand otherwise you'll end up with the clip touching some of your sensitive areas.

You can easily fit this in your pocket, jacket, purse, or bag when traveling. I had it in my pocket while I was trying to run the battery out of it and it fit inside quite easily.



Including the clip, it has an overall length of 6 3/4", but the tail curls up so it only takes up 4 1/2". The bullet section is 2 1/2" long. It has a girth of 3 3/4" around. The tail has an unstretched diameter of 1" and fully stretched it has a diameter of 2".

At first, I couldn't find any buttons to turn it on, until I realized Picobong is written sideways on the top of the bullet in raised letters. There is a + and - in the P and B of the name and that is where the controls are. I find this to be an odd placement for buttons and it's definitely not anything I've experienced before. However, once I became acquainted with it I found it very easy to use and have not had any issues with using it. I am able to feel where the controls are without looking, and do not have any issues pressing them.

To use, hold down the + to turn on the Koa, and continue holding the + to increase the vibration intensity. You cannot press the buttons to increase the power, you have to continually hold it until you reach the highest level. Once at the highest level, hold + for two seconds to go through the vibration patterns. Continue pressing the + for two seconds to cycle between the different patterns. Press - to decrease the vibration intensity or to return to continuous vibration while you're in pulsation mode. Hold the - for a few seconds to turn off the toy.



It has 12 different functions the first level is constant vibration pattern that increases in intensity, but is not considered to be very strong even at the highest setting. The other settings are as follows:

2: on-off pulses
3: fast pulses
4: faster pulses
5: fastest pulses
6: rollercoaster
7: faster rollercoaster
8: up and then down, back up and then repeat
9: wave vibration
10: increasing vibration with three fast pulses
11: increasing vibration with five fast pulses
12: random variations of patterns

Here's a picture of the patterns I found on Lelo's site.



I prefer steady vibrations, but it's nice that there is a wide selection of patterns for those who enjoy them. The vibrations are located throughout the entire length of the bullet, and are considered to be rumbly which I love and is the first bullet that I've found with rumbly vibrations. However, the power is just not there for me to be able to achieve climax. I'd consider the overall power of the Koa to be a 3 Vroom at the highest setting. I have to have a high 4 Vroom or 5 Vroom to be able to climax. I admit I wish more bullets would come with rumbly vibrations, and I do love that about the Koa. Another good thing about Koa is that no matter how long you use it, it never leaves your flesh hot and burning. I've had instances with other vibrators with this happening, but that is not the case with Koa.



When I was experimenting with it as a cock ring, the vibrations could be felt when placed on Uma, but not so much when placed on the one dildo I have. However, I was also able to test it on the amethyst to see how the vibrations traveled through glass, and I found that the vibrations could be felt on the end nearest where I clipped the Koa, but not on the end farthest away. I do not have any steel products to test this out yet so I can't tell you how it performs with that material. Overall, the vibrations travel better through my vibrators than any other object I tested. However, there's no need to make my vibrator vibrate so that is useless. I was hoping that it might give my vibrator an extra power boost, but I couldn't tell any difference when I tried it this way.



This requires 1 AAA battery to power the Koa, and the battery lasts a very long time. I tested it on high on and off throughout the majority of the day and it lasted for my testing. When the battery is fixing to die, you will notice a decrease in power and then it will shut off. I would consider it to last a good few hours of continuous use until the battery gives out, but again that depends on what setting you have it on and the intensity.

Lelo suggests to not use rechargeable batteries because doing so will result in decreased vibration intensity. So I had to test Lelo's claim in this because I so happen to use rechargeable batteries all the time and they're the only battery I use for everything. Fortunately, I had a normal alkaline battery on hand. My results are that both alkaline and rechargeable batteries give off the smae amount of power. Sorry Lelo I don't know where your validity came from, but for my case that was just not so.

To insert battery, unscrew the base attachment from the vibe right where the silicone and plastic meet. Turn counter clockwise and place the battery positive side up. Turn clockwise to shut, and make sure that it is securely closed to ensure that water won't seep in.



This is considered to be waterproof and I tested it out and it passed both inspections. I take showers so first I tested it out in the shower with me, and I did not have any issues with it. To test it submerged, I ran a sink full of water and placed the Koa in there, and it happily buzzed in circles in the sink. I did not have any issues with leakage or diminished power. According to Lelo's website, its waterproof capabilities last up to 1 meter.

It is virtually silent and can't be heard through closed doors or through thin walls.

With Koa, use only water-based lubricants. Silicone based may damage the silicone on the outershell of your toy. Never use massage oils or hand cream as a lube with this toy. Clean it with antibacterial soap and warm water and rise and pat dry with a cloth. It does not pick up as much dirt and debris as some silicone products tend to do. Avoid cleaning soultions containing alcohol, petrol, or acetone.

Lubricant and arousal creams do tend to collect in the raised letters of the name, but it washed away very easily under running water. I didn't have to use anything to dig it out so that was fantastic.

Included in the package was a user manual written in several languages, the warranty information, the Koa, and a little black dice. There was not any additional storage pouch to keep the Koa in, but I just store mine in my lingerie drawer with my other toys.

Lelo warrants this toy for one year after the date of original purchase against defects due to faulty workmanship or materials. The warranty covers working parts that affect the function of the toy. It does not cover cosmetic deterioration caused by wear and tear or damage caused by accident, misuse, or neglect. If you open the toy, it automatically voids the warranty.

Lelo included a black dice that is black and engraved with pictures of Lelo toys on it. You go to https://www.picobong.com/en/game.php and until October can play a game similar to pac man where you collect vibrators and advance to the next level, but you have to stay away from the shadow or you lose the round.

My husbands response when I showed this to him was that there was no way that I was going to clip that onto him. That's why I had to use this cock ring on my toys and use it as a bullet. As an overall toy, I feel Lelo's Koa is well made and highly crafted, but it does not have enough power for me to obtain climax with. I have to have Uma strength before I am able to climax, and the PicoBong Koa is far from Uma strength.

My most unique experience with Koa was when I clipped this onto Uma and used Uma externally and had both motors on Vr8 while using the Vr8 internally. I've never been able to climax vaginally and I wanted to see if four motors would be able to get me there. Unfortunately, that was not the case but at least I tried. I was not able to tell any difference in transfer of power to either of the toys which was sad because I was hoping I could position it to where it would transfer through both toys.

Overall, it makes a decent bullet, does half-way work as a cock ring to allow my non-vibrating toys to vibrate so I am going to give this toy a 3 out of 5 stars. I'm taking away stars from lack of power and my opinion that it wouldn't work as designed on a male penis.
