With its long length and gentle vibrations, this vibrator will be most useful for those looking for a teasing toy for couple's foreplay. And because the entire shaft is bendable and maintains its position, it's easy to maneuver by a partner, or for easy reaching during solo play. The Power Duo Balls are both quiet and waterproof, making them ideal for use it almost any setting and can be enjoyed by both partners internally and all over externally. However, a condom is recommended for anal probing.

The Power Duo Balls are a combination of body-safe ABS plastic created balls and handle and a PVC coated shaft. The balls are PU coated and feel velvety-soft and smooth. Little to no lube is needed as the material glides easily over the skin with minimal drag. Each ball does have a fine seam running the complete width, and while it is visible and detectable by the touch, it shouldn't be noticed in use unless the user is very sensitive. The balls are solid and have absolutely no give.

The PVC shaft is light and aides in making this toy watertight. The shaft is also completely smooth, but in a silky way, and has slightly more drag than the balls. However, they still would not require much lube for comfort. The shaft has no seams is a phthalates-free material.

The entire toy had no noticeable scent and is universal for both beginners to advanced and everyone in between.

Much longer than traditional toys; the Power Duo Balls come in at 15 inches in length, with 9 1/2” being insertable and 5 1/2” allocated to making the handle comfortable for gripping and holding on to. The shaft, which is actually pencil thin and very flexible, will hold whichever shape the user creates. The balls can be bent in an arc to make for easier reaching during solo, or bent so the balls are side by side, doubling the amount of vibration. The shaft itself is very thin and should not be expected to add to the stimulation in any way other than in making this toy customizable in shape.



Each of the balls is just smaller than that of a ping-pong ball and are only 1 1/3” in diameter with 3 1/2” between the two balls. The size makes this appropriate for insertion by users of all skill levels, although it may not provide quite enough stimulation for size-queens.



This toy is semi-discreet in appearance, although it begs the question, “what is that?” if seen lying around. In size, this toy is too long to be tucked away easily without being noticed unless packed in a suitcase and probably would not make a very easy traveling companion.

As indicated by the name, this vibe has 7 functions that are controlled via the push-button located on the bottom of the base. The button is small but is easily felt and pushed during use, although it can get a bit slick if your fingers have lube on them. It is simple to control this toy. Push once to turn the toy on, defaulting always to the lowest level of vibration. From there each push will advance through the 3 levels of vibration, 4 pulse patterns, and then back to “off”. Sadly, you cannot move backwards through the patterns, nor does it have an emergency shut-off feature. The patterns are as follows:

1.) low level vibration
111111111111111111111111111111111111

2.) medium level vibration
222222222222222222222222222222222222

3.) high level vibration
3333333333333333333333333333333333333

4.) fast medium pulses
2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2

5.) fast medium pulse with extended pulse every 5th beat
2 2 2 2 222 2 2 2 2 222 2 2 2 2 222 2 2 2 2 222

6.) low to high roller coaster
1122333221112233322111223332211133322111

7.) low to high slow pulses that escalate (great for teasing)
11 11 22 22 33 33 33 11 11 22 22 33 33 33

If the bottom of the base that houses this control is twisted it will open, revealing the battery compartment which will house 2 AA batteries which are not included. Battery-life with this toy is decent, and you can expect to get over an hour of use on one set of batteries.



The vibrations, even on the highest settings, would only be considered mild-moderate in intensity. The high-frequency vibes are located only in the two balls and buzz gently over the skin for excellent external stimulation and teasing and resonate when inserted. With the shaft bent so that both balls are side by side, it is possible to stimulate the entire outer labia and clit simultaneously.



If one ball is bent in an arc and the other is straight, it works great to provide light g-spot stimulation and clitoral stimulation at the same time. However, because the shaft is relatively short between the balls, this may not work to for those with deeper spots.



The Power Duo Balls are completely waterproof and can be both in the shower or bathtub for some slippery wet fun. In the shower the noise of this toy is completely drowned out, but even on land this is pretty quiet and wouldn't likely be heard through a closed door. However, in some positions it does make an almost rattling sound that can be somewhat distracting. Usually only a small adjustment is needed to quiet the rattling.

California Exotics recommends using only water-based lubes with this toy and cleaning thoroughly with soap and water between each use. However, both plastic and PVC can be used with silicone-based lubes so this is also a possibility. If you have any concerns be sure to spot test a small, inconspicuous area first to test for a material reaction. Cleaning can also be done with a universal toy cleaner. However, this material is not considered sterilizable and should always be covered with a condom if sharing with partners or inserting anally.

Storing the 7 Function Power Duo Balls can be a bit of a challenge. It does not arrive with a toy pouch and it is not easy to find a toy pouch that will fit all 15 inches of this toy. However, it is possible to find a small fabric remnant at your local craft store and simply cut to size and roll around the toy prior to storing with other toys or in a discreet location.

The 7 Function Power Duo Balls arrived in a non-discreet clear plastic recloseable clamshell with a purple polka-dot paper background that has the product name in large letters, a picture of the toy demonstrating motion, and some product highlights. Although it included no user manual, there are some very brief instructions on the back that address battery insertion and cleaning.

I think this toy adds great spice to couple's play and those looking for something to add lots of “tease” to foreplay or solo. However, neither the shape nor the vibrations are conducive for taking most users from start to finish. So those who are seeking an “all-in-one” toy, this probably isn't it.
