Over the past 6 years of doing PE, I've used a few penis lengthening devices, e.g. FastSize, SizeGenetics, and the Jes. Having given every one of these devices a fair opportunity to prove their level of performance, I've found the X4 Labs Extender to be the most comfortable, most effective, as well as least costly of all of them.
A comfort strap then goes around around this foam cylinder and straps it to the extender. This design effectively distributes the pressure over a big area of the penis, to make it way more comfortable to wear than the noose design. In fact, this device is so comfortable to wear that I sometimes forgot that I had it on.
Better, because this extender is comfortable to wear, I was able to wear it for longer time every day, which resulted in quicker gains in penis size. Over the half a year that I was wearing this stretcher, I gained an impressive 1.05" BPEL (i.e. bone-pressed erect length) in total!
This amount of increase is the most I have ever gained by using any extender. As a matter of fact, as I was using other extenders, I was complementing the effects of the devices with manual penis exercises, whereas I had stopped doing these penis exercises when I started trying the X4 Labs device, which means that this extender alone was accountable for the 1.05 inches in gain!
I only regret not having tried this stretcher earlier - otherwise I would surely have reached my target length earlier than I did. Ironically, one major reason why I had not ordered this device earlier was because of how inexpensive it was as compared to other extenders.
To finish my review of the X4 Labs extender, I've found it to be the best of all penis device I have used in the past.
