User Experiences and Testimonials
Many users of SizeGenetics mention that it feels comfortable, especially due to its unique 58-way comfort system. This design helps you wear it longer without much discomfort. Also, it comes at a lower price compared to JES Extender, making it easier on your budget.

Clinical Studies and Evidence
Both devices are backed by clinical research showing that traction therapy is the only proven non-surgical way to increase penis length. Studies reveal about 61% of users see improvements in Peyronie’s disease symptoms, such as reduced curvature. No large studies directly compare the two, but both show strong results for enlargement and curvature correction.
Remember, results depend on how regularly you use the device and follow the recommended routine. Your commitment is key to seeing the best outcomes.
Safety and Potential Side Effects
Both SizeGenetics and JES Extender are made as medical Class I devices, which means they meet basic safety standards. Using them carefully helps avoid common side effects like skin irritation or bruising. Some initial discomfort is normal but usually eases as you get used to wearing the device.
Common Concerns
Discomfort often happens when you start using a penile extender. It feels strange at first, and your skin might get red or sore. You might wonder, “Is this normal?” It is, as your body adapts to the traction. Both devices require wearing 8–10 hours daily for 3–6 months to see results, so patience matters. Price may also concern you since both SizeGenetics and JES Extender have packages ranging from moderate to high cost. Also, these devices are not meant for young adults or those with exact medical conditions, so knowing if these rules apply to you is important.
Precautions and Recommendations
Getting the right size and fitting the extender correctly can stop injuries before they start. Always follow the daily wear time suggested by the manufacturer and increase tension slowly to avoid pain. Watching your body closely helps—if numbness, sharp pain, or skin damage happens, stop using the device and talk with a doctor. Consulting a healthcare professional before starting use especially helps if you have health issues or concerns. Taking these steps keeps you safer and improves the chance of good results.
Price and Warranty Comparison
Choosing between SizeGenetics and JES Extender means looking closely at price and warranty. These two parts matter because they affect your comfort and peace of mind over time.
Cost Analysis
SizeGenetics offers a few models to fit different budgets. You might find the basic options more affordable. Their Ultimate package comes with extra comfort features but costs more. JES Extender has six models that vary in price. The higher price reflects its strong materials, like surgical steel and silicone. If you want top quality, you pay more. Does paying more always mean better value? Not always, but material quality often justifies a higher price.
Guarantees and Customer Support
SizeGenetics stands out with a 180-day money-back guarantee and a lifetime warranty. This long guarantee shows confidence. Plus, their customer support is ready to help if you have questions or problems. JES Extender has a shorter 30-day money-back guarantee for some models and a 2-year warranty. Their support is solid but not as extended as SizeGenetics’. If you want a longer safety net, SizeGenetics may fit your needs better.
Thinking about price, comfort, and warranty together helps you pick what feels right for you. After all, wearing a device every day means comfort and trust matter just as much as cost.

Maintenance and Cleaning
