That, I've read through. quite a bit over on the Rddt subforums as well. We've also performed a mining of data through the Asian various discussion servers using generic radial type of LIST devices, but none came back as positive.
Radial bursts don't seem to provide any positive gains, while focused bursts do. Focused is quite more expensive than any cheaper radial, and they are mainly applied in clinical environments. That can be quite expensive. We have 4 brothers investd in a $3.5K focused machines to use at their homes, and so far, that works. They use the machine for other purposes besides PE, but the results are more apparent, not in great significant level, but enough to be noticed compared to normal PE routines.
If they actually signed up and logged in, the keywords like SRT and 5x5x3 are all over the place. The posts are practically available as public access info. The only thing that is not available for public access is the media streaming. That is reserved for logged in members to prevent data hogging. Quite a few members actually downloaded the videos and uploaded elsewhere as well, such as adult entertainment sites. Funny that some of those basic videos are actually on YouTube. The more exposed videos got tossed very fast.
Unfortunately, automated machines and excessive force mechanics are the most dangerous methods of approaches. Controlled and manual delivered methods are safer, although it's longer. It's like comparing to good of fine-tuned bodybuilding methods with dietary implementation vs laying in a high tech chambers with mechanical and electro-stimuator devices to work your muscles for you. It doesn't work that way. It's a combination of mechanical assistant and good old manual approaches to provide proper resistant training. The penis has too much soft tissues, sensitive nerve branches and blood vessels to be going all crazy on it. Technologies came a long way, but people are using them to destroy their penises faster than before without proper cautions and common sense.
