Free weights aren't just for the gym.

The Vibro balls is a unique butt plug with a twist having moving weights within it's two bulbs to provide extra stimulation. Great for intercourse, foreplay or even wearing to your favorite exercise class as a fun/discreet little secret only you know about. Ideal for singles or couples, any gender or experience level.
Silicone, waterproof, moving balls, decent size
Messy to remove. Some may wish for larger base. A bit too long for my comfort.

This toy is a butt plug with free moving weighted steel balls inside meant for anal or vaginal use. It can be worn during sex, foreplay, around the house or even out in public for the naughty and daring. The balls provide stimulation as they move about with your body's motion. Similar in concept to ben wa balls. I for one am excited to try such a toy for a man, since we haven't had a real alternative like this before. The base is flared for safety and comfort. It's small enough to be worn beneath clothing- Even under a thong.

Material / Texture

The toy is made of silicone with a smooth soft texture and is completely waterproof. The bulbs are hollow inside and contain steel balls that move/bounce around inside when moved. This is suitable for any experience level based on size. The maximum diameter is about 1 1/4", which is maybe a little on the thicker end for a beginner, but very doable with patience and lots of lube. The toy has no odor. The toy is bendable, but somewhat rigid at the same time, but moveable between the bulbs.
    • Flexible
    • No odor
    • Not porous at all

Design / Shape / Size

The toy is 5" long and the thickest part is 1 1/4" diameter. 4 3/4" insertable length. Having two bulbs allows for maximum stimulation of the prostate/G spot and anus simultaneously and can provide interesting simulations for him and her if worn anally by the female during vaginal intercourse. The toy is small and easy to store or travel with, making it kind of discreet, but obviously not discreet if left sitting out in the open.

The shape is good or bad depending on how deep you like being penetrated and where your joy spot is located.

The toy looks and feels great and has a nice heft to it. It's unique, smooth and body safe silicone. I was looking forward to this toy quite a bit, but for me it's just a little too long or the shape just doesn't do it for me. The first nub felt good inserted, but the second made the first push too far inside for my comfort zone. It felt like it was pushing on the end of my rectum. Maybe just a bit beyond my insertion limit. My happy P zone is just a few inches inside and I usually find butt plugs pleasant and stimulating, but this toy shape/length or combo of just didn't work for me unfortunately. If the nubs were closer together or there was just one bigger nub/ball and/or a curved shape, it would have been ideal for me. I didn't really notice any movement of the balls, but I removed it due to discomfort after trying it out.
    • Discreet sound
    • Easy to use
    • Not very discreet

Care and Maintenance

This toy can be washed with toy cleaner, 10% bleach solution, boiled in hot water or tossed in the dish washer. It's 100% silicone exterior with no electronics. It can be stored in the included pouch to keep it dust/lint-free.
    • Easy to clean
    • Easy to store
Follow-up commentary
This one just didn't work for me. Penetration was too deep for comfort, and I really didn't find the balls very stimulating. A design tweak might make a difference, or just a one bulb butt plug design would have been better for me. Kinda missed my P-spot.
