Penis Extender Upgrade Kit
Like software, you need upgrades that are compatible with the components of your operating system. X4 Labs extender universal upgrade kit delivers this compatibility with no snags attached!
Your X4 Labs universal upgrade kit includes 2 comfort straps, 2 adjustment screws, memory foam padding, and the universal hybrid support piece.
Comfort Straps
The comfort straps you get with your upgrade kit were developed using the advanced comfort strap technology of X4 Labs. This technology includes the following features:
- Comfortable “hold and hug” feature – the one-inch width of the straps allows for flexible maneuvering and adjusting. Straps in the market today are designed with a view to economizing on materials. X4 Labs wants to ensure that the wearer is not in any way short-changed when it comes to comfort.
- Compatibility with all extender models – X4 Labs extender comfort straps will fit into whatever extender edition you have. The 3-in-1 hybrid support accommodates comfort straps to a T without any added adjustment.
Adjustment Screws
X4 Labs has carefully selected its screw manufacturer so that the screws that come with your upgrade or extender edition package carry the assurance that they meet all norms and standards. Your extenders are made in Canada. This means you have the company’s guarantee that they comply with manufacturing rules. In addition, the tiny components that hold your extender and make it work – like the screws – are also factory-compliant.




This product review for the x4 Labs extender is based on an interview with the president of X4 Labs Rick Oh, x4 Labs founder and president. He has been pleased with the public’s approval of the x4 Labs extender. Although he thinks the entire product line deserve equal praise, he agreed to talk about the gold premium edition, the signature product that evolved from a lengthy research study. “It isn’t over, our clinical study will continue indefinitely because we want more men to participate and provide valuable feedback”, he said.
