Product Review:

As with similar devices the X4 Labs penis extender works on the principle of "traction" to successfully increase both the girth and length of the penis. Over the months of use "traction" breaks down and creates new skin cells in the penis, increasing size. The X4 Labs penis extender is fitted with something they call comfort strap technology as well as the more traditional rubber tubing support. Our reviewers found the Comfort Strap Technology more comfortable than rubber tubing, but with the X4 Labs device you have a choice of your preferred method.

The comfort strap system makes it easy to wear for extended periods of time, such as when you're sleeping, and can even be worn under your clothes. Several of the male enhancement devices listed on are very similar in design but the ones with the Comfort Strap-Hybrid Extender System are by far the most efficient extenders available. The X4 Labs male enhancement system increases penis length and girth by up to 35%, and our reviewers found no issue with this claim as it is backed by several scientific studies. And don't forget with a penis extender the results are permanent!


The X4 Labs brand is backed by a 6 month Penis Growth Guarantee and the makers claim a 95% success rate, so we have no doubt that they have the confidence to stand by their product and its results. X4 Labs have great customer service with phone and email customer support agents on hand to help with any questions you have.


What makes the X4 Labs penis stretcher effective is that they comfort strap allows you to use it for an extended period of time. Our reviewers found that it could even be worn comfortably under their clothes. With a scientifically backed 35% increases in both penis length and girth we are confident that these results can be realized by most men. As your penis grows the X4 Labs extender can be easily adjusted with the included longer extension bars to further increase results.

The Verdict:

X4 Labs male enhancement devices are the best extender products for a non-surgical option for male enhancement, and the scientifically proven results are not to be ignored. We are happy to rate this device as our No. 1 extender, with the bonus of a free penis exercise guide and free male enlargement pills available with some of the value packages.
