## Emma's take

Real-feel silicone that vibrates while you wear it.

This vibrating extender caught my attention for its FLEXSKIN material — it genuinely feels different than standard silicone, more skin-like and warming. The wireless remote means your partner can control the eight vibration modes while you wear it, which turns the whole experience into shared play rather than solo enhancement. At 6.9" insertable with nearly 7" total length added, it's a confident size boost that works best for couples who've talked through the change beforehand.

## Frequently asked questions

## How much length and girth does this add?

The extender adds 6.9 inches of insertable length to your natural size, with moderate girth enhancement. The internal diameter is 1.6 inches to accommodate most wearers comfortably.

## What makes FLEXSKIN different from regular silicone?

FLEXSKIN is Shaft's proprietary liquid silicone that warms to body temperature faster and has a more skin-like texture than standard silicone. It's designed to feel more realistic during wear and use.

## Can I control the vibrations myself or does my partner need to?

The wireless remote can be used by either partner. It has 8 vibration patterns plus a boost function, and the remote is waterproof for shower or bath play.

## Do I need to be erect to use this extender?

This extender works best with at least some firmness for secure fit and comfort. The internal sleeve is designed to accommodate and enhance your natural state rather than replace it entirely.

## How do I clean this properly?

The extender is fully waterproof — wash with antibacterial toy cleaner and rinse thoroughly. The remote is splash-resistant but shouldn't be fully submerged. Always use water-based lube to protect the FLEXSKIN material.

## Is this comfortable for extended wear?

The FLEXSKIN material is designed for comfort, but like all extenders, it's best for session-length wear rather than all-day use. Take breaks as needed and listen to your body.
