Balldo Australia - Unique Ball-to-Penetrator Male Sexual Enhancement Devices

Nadgerz is the company behind Balldo, a silicone ball dildo that lets the wearer penetrate with the testicles. Its range covers the original Balldo, the vibrating Viballdo, and spacer rings that adjust firmness and reach.

About Nadgerz

Nadgerz was founded by engineer Jerry Davies and co-designer Elizabeth Plasencia. Davies noticed there was enough slack at the top of the scrotum to shape a second shaft. Over three years the pair built more than 100 prototypes before settling on the Balldo design.

The Balldo was crowdfunded on Indiegogo in just 10 hours in March 2021, and shipped to trade from August 2021. The idea drew press from Vice, Wired and Cosmopolitan. A vibrating version, Viballdo, followed in 2023. In August 2026 the design was granted a US patent.

Nadgerz brands

Nadgerz sells under two brands.

Balldo

Balldo is the original ball dildo, launched in 2021. A stretchy silicone cage holds the testicles, and a tapered tip about the width of an average penis extends from it. A strong inner core keeps it firm for penetration. Each set includes the Balldo and two spacer rings, in purple or grey. Use plenty of water-based lube on the tip and on your partner.

Viballdo

Viballdo is the vibrating version, crowdfunded on Indiegogo in 2023. A motor in the soft tip runs 10 programs, and vibration also travels down the legs of the cage. Both the wearer and the partner feel it. Compared with Balldo, it has a shorter cage, softer and stretchier silicone, and a longer tip. Charge it fully before first use, and keep the tip clean.

Nadgerz categories

Accessories round out the range.

Spacer rings and ball stretchers

Single spacer rings sit above the Balldo or Viballdo and brace it against the body, so it stands firmer and reaches further. Most people start with the two included rings and add more if there is extra skin to fill. The same rings work on their own as ball stretchers, sold singly or in four-packs. Add one ring at a time, and stop at a comfortable fit.

How a ball dildo works

The Balldo slips over the scrotum like underwear, with the stretchy upper ring sitting at the top. The testicles sit inside an open cage, with the tip extending forward. Spacer rings above the cage brace it against the abdomen, so it stays firm like an erection. Because it does not rely on the penis, the wearer can enjoy a different kind of penetration.

Getting the fit right

Fit depends on how much loose skin sits above the testicles. Start with the two rings in the set. If the Balldo still wobbles, add a single spacer ring and test again. Some people use several. The aim is a firm, stable shaft that still feels comfortable.

Bodies are all different

No two bodies are the same, and that matters for fit. Our guide to penis types looks at the range of shapes and sizes. Our surprising penis facts covers a few things most people never learn, including how the scrotum moves with temperature. A warm room and a relaxed body make the Balldo easier to put on.

Sexual health and confidence

Good sexual health supports a good sex life. Our article on men’s sexual health supplements looks at which supplements have real evidence behind them.

How Nadgerz products compare

Here is how the brands and accessories line up.

Choosing your first Nadgerz

For a first try, choose a Balldo set, which includes everything you need. If you and your partner love vibration, choose Viballdo. If your Balldo feels short or loose, add single spacer rings. The wearer’s penis stays free, so cock rings can add firmness there, while penis sleeves add length and texture for double play.

Using it as a couple

Talk about it first, as ball sex is new to most people. Use plenty of lube and let the receiving partner guide the depth and pace. Go slowly at first, as the shape moves differently from a penis. Check in often. Many couples find it adds laughter as well as pleasure.

Caring for your Nadgerz

Wash the Balldo and rings in warm, soapy water or with a sex toy cleaner after each use. For Viballdo, keep the charging port dry. Dry everything fully before storing. Keep it away from other silicone products, which can mark the surface.

Who Nadgerz suits — and who should look elsewhere

Nadgerz suits curious couples who want to try something new, and wearers who want a different way to penetrate. It also suits fans of ball stretching, thanks to the spacer rings.

It is not for anyone who wants a strap-on harness or a hollow sheath. People with very little loose skin may struggle to get a stable fit.
