How the Devices Work

Just like other penis extenders, the PeniMaster and the PeniMaster Pro promise results based on the fact that muscles tend to grow and expand when subjected to long-term stretching and stimulation. New cells and tissues form when the penis gets worked out regularly. 2

Penis enlargement is very similar to the principle of body-building. The more you work out those muscles, the larger and firmer they grow. The same concept applies to penis enlargement. The more you stretch, stimulate, and work out the penis, the harder and bigger it grows.

It goes without saying that the gains you are going to get will greatly depend on the time and effort you invest in using the devices. Commitment is the key to getting the most out of penis extenders.

How to Use the Devices

If you have used other penis extenders before, applying the PeniMaster or PeniMaster Pro shouldn’t be that confusing. The procedure is basically the same with a few minor changes.

The main steps in applying the PeniMaster are as follows:

  1. Using the extension rods, you adjust the device based on the length of your flaccid penis.
  2. Insert your penis through the base ring then slowly wrap the comfort belt right around the section where the head and body of your penis meet.
  3. Strap in the penis by attaching the holding belt through the slits in the support base.
  4. Carefully push the extension rods up into the support base. Click them into place and you are done.
  5. You can adjust the pulling strength of the device by turning the thread of the gadget’s pull-control mechanism.

It becomes more complicated if you avail of the PeniMaster Pro. The Pro comes with two application systems – the pump ball application system and the hose application system. The complete instructions on how these systems work can be found in the manual that comes with the product.

If you have questions on how to use the extenders, the package comes with a detailed and illustrated user’s guide. You can also visit the official website for additional videos and more instructions.

How Long Should You Use the Extender?

Always keep in mind that when it comes to extenders, getting the results you want is often about using the extender as often and as long as you possibly can. The more you wear it, the more gains you will receive.

According to the manufacturers of the PeniMaster extenders, the ideal number of hours to be wearing the extender is between 6 and 12 hours. You are going to basically wear it for most of the day. However, some men have claimed to have seen significant results even though they wore the device for less than 6 hours a day.

The manufacturers also advise that you use the extender in durations. This means that you don’t have to wear it for 6 straight hours. For example, you can wear it for 3 hours in the morning then wear it for another 3 hours in the afternoon.

You can further break down the 3 hours. For instance, wear the device for an hour then give it a pause for 5 to 10 minutes before strapping it back on. This allows blood to circulate in your penis and stimulate cell and tissue growth.

Night Usage

Yes, you can definitely use the PeniMaster Classic and the PeniMaster Pro while you sleep. But do it with lower settings since you won’t be waking up every hour to relax your penis muscles. The manufacturer actually doesn’t recommend using the extender at night while you sleep.

But if it’s the only time that you can apply the system, the manufacturers say you can but do it with moderate settings so as not to put too much pressure on the penis.

  • They are more complicated compared to other extenders in the market. They have more working parts. This means they are more difficult to apply. They are also a bit more difficult to remove, clean, and store.
  • They only come in white color. Discoloration can be a huge problem. The genital area is a cesspool of germs and microbes. These can create stains in the extender even if was only used a couple of times.
  • They have lacklustre customer support. They don’t seem to have an efficient support system for customers. The only way to send a query or a complaint is via email which we all know is an inefficient method in answering customers.
  • You have to wear the device for hours daily to see results. The manufacturer recommends between 6 to 12 hours of daily usage for maximum results. That’s a lot of time to be wearing a device strapped onto your penis.


The results you get from using PeniMaster extenders depend on various factors. The most important of these factors are total wearing time, individual physiology, and amount of force applied. Some men are just more responsive to these extenders.

You don’t have control over your physiology but you have control over the amount of time you use the extender. Again, those who use the device more often get better results. To get the best results, try to follow the recommendation by the manufacturers of the device. Apply the extender for 6 to 12 hours a day.

Results vary from person to person. Some men say they gained 2 inches after 6 months of application. Some claim they gained only a half inch. And of course, there are those who say they didn’t gain anything. 3
