Motorbunny Attachment Materials: TPE vs. Silicone vs. Dual-Density – Which Should You Choose?

Quick answer

For most Motorbunny owners, silicone attachments are the easiest to clean and most durable, but TPE offers a softer, more realistic feel. Dual-density designs, like the Vac-U-Lock ULTRASKYN cock, blend a soft exterior with a firm core for a lifelike experience. Choose based on your priority: easy maintenance, realistic texture, or intensity.

When you're shopping for Motorbunny attachments, the material matters more than you might think. It affects how the toy feels, how easy it is to clean, and how long it lasts. TPE, silicone, and dual-density are the three main options, and each has its own strengths and trade-offs.

In this comparison, we'll break down what each material offers, using real Motorbunny products as examples. By the end, you'll know which attachment material fits your play style, cleaning habits, and intensity preferences.

TPE Attachments: Soft and Realistic, but Porous

TPE (thermoplastic elastomer) is a popular choice for attachments because it feels soft and fleshy. The XL TPE Cover, for example, is designed to slip over the standard TPE attachment to add length and girth. It measures 6 inches in length with a 5.6-inch circumference, and it comes in a realistic flesh color. This material is great for users who want a more lifelike sensation without the firmness of silicone.

However, TPE is porous, which means it can absorb fluids and harbor bacteria if not cleaned properly. It also requires water-based lubricant to fully affix the cover onto the attachment, as noted in the product details. TPE attachments are generally less durable than silicone and may need to be replaced more often. If you choose TPE, be prepared for extra care and a shorter lifespan.

• Use water-based lubricant with TPE to prevent damage and ensure a secure fit.
• Clean TPE attachments immediately after use with mild soap and warm water, and allow them to dry completely before storage.

Silicone Attachments: Non-Porous and Easy to Clean

Silicone is a premium material that is non-porous, making it hygienic and easy to sterilize. The Motorbunny Original Flat Silicone Attachment is made of 100% body-safe silicone and features a clitoral stimulation nub. It's compatible exclusively with the Motorbunny Original, and its pink color is designed for easier cleaning and higher durability.

Silicone attachments are firm, which can deliver more intense vibrations. They're also more resistant to wear and tear, making them a long-term investment. The main drawback is that silicone can be too firm for some users, especially those who prefer a softer, more realistic feel. Additionally, silicone attachments are not compatible with silicone-based lubricants, so you'll need to stick with water-based options.

• Silicone attachments can be boiled or wiped with a 10% bleach solution for thorough sterilization, but always check the manufacturer's instructions first.

Dual-Density Attachments: The Best of Both Worlds

Dual-density attachments combine a soft, realistic exterior with a firm inner core, offering a lifelike feel that's still supportive. The Vac-U-Lock 8-Inch ULTRASKYN Cock is a prime example. Made from ULTRASKYN, it features a dual-density design with a soft exterior and firm core, molded directly from a real erect penis. This gives you the comfort of soft skin with the stability needed for machine use.

Dual-density attachments are often more expensive than single-material options, but they provide a unique sensation that many users find worth the investment. They're also phthalate-free and body-safe, as stated in the product facts. If you're looking for a realistic experience without sacrificing performance, dual-density is a strong contender. However, like TPE, ULTRASKYN is porous and requires diligent cleaning.

• Dual-density attachments are ideal for users who want realism but still need firmness for intense sessions.

Trade-Offs to Consider

• Cleaning and Maintenance: Silicone is non-porous and can be sterilized easily, making it the lowest-maintenance option. TPE and ULTRASKYN are porous, so they require thorough cleaning and may harbor bacteria if not dried properly. If you're short on time or want maximum hygiene, choose silicone.
• Realism and Feel: TPE and dual-density attachments offer a softer, more realistic texture. The Vac-U-Lock ULTRASKYN Cock is molded from a real penis and has a dual-density design for a lifelike feel. Silicone is firmer and less realistic. For the most realistic experience, go with dual-density.
• Intensity and Vibration Transmission: Silicone is firmer, so it transmits vibrations more directly, which can be more intense. TPE and dual-density materials absorb some vibration, softening the sensation. The Premium Silicone Mt. Gushmore Attachment uses a wave design to maximize vibration for grinding, showing how silicone can enhance intensity. If you crave strong vibrations, silicone is your best bet.
