#4 Rated Penis Extender: JES Extender
The Jes Extender has been on the market for over 10 years. This proven and effective penis extender is amongst the top brand names in penis enlargement and is the original penis extender design.
What is JES Extender?
If you never heard of the Jes Extender, you probably heard of its re-branded counterparts. The Jes Extender has been re-branded by some other familiar names like Size Genetics. The copied versions of the Jes Extender are extremely popular but of course anything that’s a copy of the original isn’t always quite as good. Does this mean the copies aren’t as effective? Not necessarily. Copies are an homage to the original, sometimes doing the original justice and other times failing to hit the mark by just millimeters. Regardless, imitations are the sincerest form of flattery and goes to show you how good the Jes Extender was. The Jes Extender is effective, is the original design but has not been updated in over 10 years.
Our Ratings for JES Extender
What Makes the JES Extender Number #4?
The JES Extender stands as the original penis extender design that has stood the test of time. Its enduring popularity comes from its proven effectiveness and solid construction. What makes this extender rank at number four is its traditional approach to penile enhancement – a system that works but hasn’t evolved significantly in recent years while competitors have innovated.
The JES Extender utilizes a traditional traction approach that gradually stretches the penis, promoting cellular division and growth over time. While effective, its single-strap design and steel construction present some comfort challenges compared to newer models. The device provides up to 1500g of tension force, which is sufficient for most users’ enlargement goals.
Performance and Results
The JES Extender has proven performance with users reporting average gains of 20-25% with consistent use. The device’s design, while traditional, delivers reliable results by applying constant traction to the penis, stimulating cellular growth over time. The effectiveness of the JES Extender is backed by years of testimonials and clinical studies.
One drawback in performance is the single-strap design, which can lead to slippage during use. This means more frequent adjustments may be necessary compared to newer dual-strap systems on the market. Despite this limitation, dedicated users still achieve significant enlargement results with proper application and consistent wear.
Comfort and Wearability
Comfort is where the JES Extender falls somewhat short compared to newer models. The device’s steel construction, while durable, adds significant weight that can cause strain during extended wearing periods. The single-strap design requires more frequent adjustment and can lead to slippage issues that interrupt the extension process.
The manufacturer does include extra gauze to minimize chafing, which helps improve the comfort factor. However, the bulky base makes the device difficult to wear under fitted clothing or jeans, limiting when and where you can use it. For those seeking a more discreet option that can be worn throughout the day, newer models might offer advantages in this category.
Value and Cost Considerations
The JES Extender price range starts at $249 and goes up to $1399 plus shipping, depending on the model and package chosen. This places it in the mid-to-high range of penis extenders on the market. While the device does offer solid construction and proven results, the price point is relatively high given its dated design and limited included accessories.
One value consideration is that the JES Extender comes with limited extension rods and accessories, potentially requiring additional purchases to achieve optimal results. This increases the overall cost of ownership compared to competitors that include more comprehensive accessory packages. The quality of construction does ensure longevity, however, making it a long-term investment for those committed to the enlargement process.
Customer Service and Privacy
The JES Extender scores highly for customer service and privacy considerations. The company provides discreet shipping with no indication of the package contents, ensuring complete confidentiality for customers. The customer service team is responsive and knowledgeable, offering support throughout the purchase and usage experience.
The company also offers a money-back guarantee and warranty, providing peace of mind for customers making what is a significant investment. Documentation is clear and informative, helping users get started quickly and safely with their enlargement routine. All these factors contribute to a positive overall customer experience despite some limitations in the product itself.

Final Thoughts
The JES Extender is well made and sturdy but also bulky and heavy. It works well with men reporting average gains of 20-25%. Unfortunately, the design is quite dated and needs to be refreshed. The JES Extender provides up to 1500g force tension, comes with very limited spare parts or accessories. Extra items can be purchased from the JES website as needed. Overall, the documentation is clear and informative. The device is well packaged for hygienic purposes and they also add extra gauze to minimize chafing, a nice touch that appears to elude other manufacturers.
Their motto appears “if it ain’t broke, why fix it” but with so many existing models to choose from, more versatile effective and cheaper penis extenders can be found as a great alternative. If you are familiar with the JES Extender then you already know you can’t go wrong, if you got the extra money to burn. Given the combination of proven results but dated design, we’ve rated the JES Extender at 8.3 out of 10 stars, placing it fourth in our rankings of penis extenders in 2024.
