The quality of Jes Extender products is excellent. Danish manufacturing is second to none (other companies - mainly Chinese ones, are just copying their design and then using poor quality materials), and their products act just as advertised. I highly recommend them.

At first, I wasn't sure how much change to expect, but after a few weeks, I'm seeing real results. It's easy to wear, and the gradual progress keeps me motivated. Totally worth it

I've used the JES-Extender for over a year initially and found it very helpful. I didn't use it every day but about five days a week for 2-4 hours at a time. I’m sure I would have gotten quicker results if I had used it for the time recommended each day. During the first 6 months, it not only helped to greatly improve the slight curvature I had but also added back about not quite an inch, which I had lost as I got older. So, I was back to feeling 30 y/o again, at least in that area. The Extender added even more length as I continued to use it. One of the unexpected rewards of the JES-Extender was that it increased sensitivity overall, which helped my performance. From what I have read, the benefit of more sensitivity was probably because of the increased blood flow it produces. I highly recommend the JES-Extender. It will not only help your confidence and performance; but you will likely have a more enjoyable life with your partner. I continue to use it regularly. I have to say their Customer Service is excellent. They are very helpful when emailing and give accurate, prompt and courteous replies. They always had whatever I ordered to me in just a few days.

Absolutely ineffective. I feel all these reviews are only written by marketing people. Been using the device for 10months, wearing it every single day without a fail for at least. 3-4 hours, and haven’t grown a mm.

Jes Extender stands out because of how comfortable it is. I've used others that felt awkward, but this one is easy to wear for hours. After two months, I can see noticeable improvements.

The initial delivery of the device was impressively fast. When I later ordered additional extenders, the shipping took longer, but overall, I’m satisfied with the delivery service. As for the device itself, the experience has been positive. It took me a couple of weeks to perfect my method, but now I can put it on and wear it for hours without any issues. While it's not the most comfortable, it does the job effectively.
