Nadgerz Balldo, Viballdo & Silicone Ball Dildos

About Nadgerz

Nadgerz Inc. is the company associated with the Balldo and Viballdo adult toy brands. Its products are distributed internationally through Balldo's website and adult retail partners.

The Balldo concept was developed by engineer and company co-founder Jerry Davies, working with co-designer Elizabeth Plasencia. The original idea centred on using the loose tissue around the scrotum to support a separate penetrative shaft.

The development process took approximately three years and involved more than 100 prototypes. The aim was to create a wearable silicone structure that could hold the testicles while supporting an insertable tip without relying on a conventional strap-on harness.

Balldo was crowdfunded through Indiegogo in March 2021. The campaign reached its funding target in ten hours, and trade distribution began on 30 August 2021.

The concept attracted attention from publications including Vice, Wired and Cosmopolitan. A vibrating version, Viballdo, followed with a crowdfunding campaign in 2023.

Nadgerz received a nomination for New Pleasure Products Company of the Year at the 2021 XBIZ Europa Awards. The company continues to concentrate on its distinctive ball dildo system and related silicone accessories rather than operating a large collection of unrelated adult toy brands.

Nadgerz Brands and Product Range

Nadgerz has two main named products, Balldo and Viballdo, alongside silicone spacer rings and ball stretcher accessories. Their differences relate primarily to vibration, silicone flexibility and the supporting cage design.

Balldo – How the Original Ball Dildo Is Constructed

Balldo is built around a scrotal cage with a separate insertable shaft. The testicles sit within the flexible cage, while the upper ring rests around the area above the scrotum.

The forward-facing shaft provides the penetrative section. A firmer internal core helps the shaft retain its shape, while the surrounding silicone cage provides flexibility around the wearer.

Unlike a conventional dildo with a suction-cup base, Balldo is supported by the wearer's anatomy. Unlike a penis sleeve, it does not need to cover the penis to provide an additional shaft.

The original design includes two spacer rings in the set. These accessories affect how the cage is supported and can change the stability of the forward-facing shaft.

Balldo is described as being made from phthalate-free silicone. Insertable diameter can vary by version, so buyers should check the dimensions on the relevant product page.

The construction can provide a different physical experience from conventional penetrative sex toys, but compatibility depends on anatomy, fit and comfort. Not every wearer will have sufficient loose scrotal tissue for a stable fit.

Viballdo – Powered Vibration and Updated Silicone Design

Viballdo builds on the original Balldo concept by adding powered vibration. The motor is positioned within the softer insertable tip and provides ten vibration programs.

According to Nadgerz's product description, vibration also travels through the supporting silicone cage. This means the powered movement is not limited entirely to the external tip.

The company also changed the physical proportions of the original design. Viballdo has a shorter cage and longer tip, with silicone described as softer and more elastic than the original Balldo construction.

These changes may affect how the product sits against the body, but they do not guarantee that Viballdo will provide a better fit for every wearer.

Viballdo should be compared according to its actual insertable dimensions, cage flexibility, vibration settings and charging method.

For customers choosing between the two models, the main distinction is straightforward: Balldo provides the original non-vibrating construction, while Viballdo adds ten vibration programs and a revised silicone design.

Nadgerz Silicone Spacer Rings and Ball Stretching

Spacer rings are central to the Nadgerz system because the ball dildo needs to remain supported against the body. The rings are designed to alter the position of the silicone cage and improve stability where the wearer's anatomy permits.

The Balldo set contains two rings. Separate rings are available individually or in packs of four, providing additional fitting options without requiring a completely different ball dildo.

Nadgerz also markets these rings as standalone ball stretcher accessories. When used separately, their purpose differs from supporting a penetrative shaft.

A ball stretcher surrounds scrotal tissue and may create a stretching or downward-pressure sensation. A conventional cock ring is positioned differently and should not be assumed to use the same dimensions.

Adding more rings is not automatically better. Excessive compression can cause pain, swelling, circulation problems or skin irritation. The fit should remain comfortable, and the accessories must be removed immediately if numbness, coldness or colour changes occur.

Nadgerz spacer rings are purpose-designed for the Balldo system. Buyers should not assume that unrelated cock rings or rigid metal rings can substitute for the manufacturer's specified accessories.

Balldo vs Viballdo – Product Comparison

Balldo and Viballdo share the same basic scrotum-mounted concept, but they differ in their construction and stimulation features.

How Nadgerz Differs From Conventional Cock Rings

Nadgerz products are closely associated with male anatomy, but Balldo and Viballdo are not ordinary cock rings. Their main function is to support a scrotum-mounted dildo rather than simply forming a ring around the penis.

A conventional silicone cock ring usually fits around the penis or the penis and testicles, depending on the design. Nadgerz uses a larger supporting cage and spacer rings to create a different wearable configuration.

Customers exploring related flexible products can compare silicone cock rings. Flexible rings vary in diameter, stretch and whether they include vibrating components.

Rigid steel cock rings have a different construction because they do not stretch around the body. They are not direct substitutes for Nadgerz silicone spacer rings.

The distinctions matter when comparing fit. A spacer ring intended to support Balldo should not be selected using measurements intended for a rigid penis-base ring without specific manufacturer guidance.

Balldo Compared With Penis Sleeves and Male Strokers

Balldo differs from a hollow penis sleeve because its insertable shaft is supported by the scrotal cage. A penis sleeve typically fits over the penis, while a manual male stroker is moved along the shaft to provide textured contact.

The wearer's penis remains separate from the Balldo's forward-facing shaft. This creates a different arrangement from a conventional sleeve designed to add external girth or texture directly to the penis.

Its core range is the original ball dildo, the vibrating version and supporting silicone rings.

For a separate male masturbation option, browse male strokers. These products should be compared by sleeve length, internal texture, material and whether the mechanism is manual or powered.

Balldo and Male Chastity Devices – Different Purposes

Balldo and Viballdo contain a scrotal cage, but that terminology should not be confused with a locking male chastity cage.

The Nadgerz cage supports the testicles and an insertable shaft. A conventional chastity cage is designed to enclose part of the penis and may include a locking mechanism.

These products therefore differ in their intended purpose, dimensions and wearing arrangements.

Nadgerz Patents, Trademarks and Product Development

Balldo's unusual construction is associated with both trademark and patent records.

The BALLDO trademark was registered in the United States on 20 June 2023 under Registration No. 7,087,491, covering sex toys and scrotal dildos in Class 10.

Trademark records identify ECJ Products Ltd of Poole, United Kingdom, as the recorded trademark owner. Nadgerz remains the company associated with the Balldo and Viballdo product brands.

US Patent No. 12,708,548, titled Device for attachment to a scrotum, was granted on 18 August 2026. The named inventors are Elizabeth Plasencia and Jeremy Davies.

The patent relates to the product's attachment concept. Patent registration does not independently certify material safety, establish medical approval or guarantee that the design fits every body.

Nadgerz also received a 2021 XBIZ Europa Award nomination for New Pleasure Products Company of the Year. This is industry recognition rather than a safety certification.

Nadgerz Materials, Lubricants and Product Care

Balldo, Viballdo and their spacer rings are described as using phthalate-free silicone. The original Balldo combines a flexible outer cage with a firmer internal shaft structure, while Viballdo uses softer silicone around its revised design.

Silicone-based lubricants can be incompatible with some silicone sex toys. A suitable water-based lubricant is generally the practical starting point, subject to the manufacturer's instructions.

Clean the Balldo and compatible silicone spacer rings after use using the cleaning method specified by Nadgerz. Warm water and a mild soap may be suitable where permitted by the manufacturer.

Viballdo contains electronic components and therefore requires additional care around its charging system. No specific waterproof rating is published, so buyers should not assume the complete vibrating unit can be immersed.

Allow all accessible surfaces to dry before storage. Store the products away from excessive heat, sharp objects and materials that could mark or damage their silicone surfaces.

For products intended for penetration, cleaning and material compatibility are separate from insertable safety. Check the shape, dimensions and appropriate retention or retrieval features before considering any insertable toy for anal use.

Choosing Between Balldo and Viballdo

For the original design: Balldo provides the non-vibrating scrotum-mounted dildo with a flexible cage and supporting spacer rings. Its main function is mechanical penetration without an electronic motor.

For powered vibration: Viballdo adds a vibrating tip with ten programs. Its shorter cage and softer silicone also distinguish it from the original model.

For additional fitting accessories: Nadgerz offers individual spacer rings and four-packs. Ring compatibility and the intended body fit should be confirmed before purchase.

For a conventional penis toy: A regular cock ring, penis sleeve or male stroker may be more appropriate if the user specifically wants stimulation centred on the penis rather than a scrotum-mounted dildo.

Buyers should also consider the receiving partner's preferences, the product's actual insertable measurements and whether the wearer can achieve a comfortable fit without excessive pressure.
