Penimaster Pro uses a mix of straps, rods, and vacuum technology. You wear it under clothes. Some find it easy to hide. For example, one person wore it at work without others noticing. Does it feel odd at first? Yes, but users often say it gets better in a few days.
SizeGenetics uses a strong but flexible frame and comfort straps. Clinical studies from Denmark prove that it can help with both length and girth. If you look at real numbers, men saw an average gain of 28% in length and 19% in girth after 4 to 6 months. It also helps with penile curvature—for men who struggle with that. Some say they got stronger erections because of better blood flow too.
What do both share? Both can be worn during daily activities. Both work best if you use them every day for a few hours. For example, you might split use up: three hours in the morning and three at night.
What makes them different? The biggest difference is the way they hold the penis. Penimaster Pro uses a vacuum to hold the head. SizeGenetics uses a comfort strap. Which feels better? That’s a personal thing. Some like the vacuum for less pressure. Others prefer the simple strap system.
Looking for medical backing? Only SizeGenetics cites clinical studies showing real size gains, stronger erections, and a safe profile when used as instructed.
Trying to pick one? Both help men who want natural gains with safe, slow progress. Have you thought about what feels most comfortable to you? That’s worth thinking about before you choose.
Design and Comfort Comparison
Trying out a new device? You want one that feels good and is easy to wear. Penimaster Pro and SizeGenetics look much the same, but they work and feel very different on your body.
Device Materials and Build Quality
Penimaster Pro holds your penis with a gentle vacuum. You don't see metal parts pressing on your skin. This vacuum system helps stop pinching, so you can wear it longer in comfort. It gives you a soft fit, and men often wear it under pants without any trouble. Both a belt and rods can keep it in place, so you pick what's best for you.
SizeGenetics uses stainless steel rods and a strong frame. The straps that hold your penis come in a few shapes, like a noose or a wide band. Metal makes this device heavy, but it can last for years. The whole set fits into a neat box, so you get a feeling that every part matters. Extra padding and foam let you add comfort where you want.
Ease of Use and Wearing Experience
Penimaster Pro lets you choose how to wear it. Some men use the rod system at home. Others pick the belt for day wear at work or while walking. The vacuum secures your penis softly, which keeps it from slipping out. Most people say it doesn't hurt, even if you wear it for four or more hours.
SizeGenetics has many ways to adjust. You twist the rods to change how much it pulls. Padding and straps help you find a grip that works just right. Some men say the device can get heavy. If you sit for a long time, you might feel the weight. The box has guides and videos, making first use much easier.
Do you want a lighter feel, or do you like firmer setups? Penimaster Pro feels soft and light, thanks to no squeezing. SizeGenetics stands out with more ways to adjust pressure and fit.

Adjustment Options
Both devices let you change how much they stretch. Penimaster Pro has a vacuum part, plus both rod and belt setups. This gives you choices—you can keep it on while sitting, walking, or relaxing at home. You adjust the settings with small turns and the vacuum lets you stay snug without slipping.

Effectiveness and Results
Both Penimaster Pro and SizeGenetics use stretching to help make the penis longer. They work in different ways but aim for similar results. Are you wondering which device really works best? Let’s look at real stories and research.
Clinical Studies and User Feedback
Many users want to hear from others before trying something new. Penimaster Pro uses a vacuum and belt or rod system. People say it feels gentle and the stretch is steady. Have you ever tried a device that slips? Most users say Penimaster Pro stays put, with little pain. Still, some notice its parts feel light, almost fragile. That could make you worry about long-term use.
SizeGenetics gets a lot of trust for one big reason—it’s backed by doctors. Clinical studies show that men using SizeGenetics saw their penis grow longer and thicker. Some found their penis got 28% longer and 19% thicker in just 4 to 6 months. Users like the metal build because it feels sturdy. Others say the device is heavy but doesn’t break. You can adjust tension quickly without taking it off. Sounds easier, right?
Expected Timeframe for Results
How fast can you see a change? A study from the Mayo Clinic says men can get about 2 centimeters longer after six months of gentle use with a traction device. That’s not overnight speed, but it’s real.
If you use these stretchers every day, most people need at least a few months to notice results. Sticking to the routine matters. You might notice small changes in just a few weeks. Bigger gains, like those from clinical tests, come after four to six months. Would you stay patient for that long? Most successes come from people who make it a steady habit.
Here’s a quick look at what users and studies report:
Device | Reported Average Gains | Timeframe | Main Features |
---|---|---|---|
Penimaster Pro | Not clearly reported | 3–6 months | Vacuum hold, light feel, flexible |
SizeGenetics | Length 28%, Girth 19% | 4–6 months | Strong build, quick tension adjust |
Traction Devices (General) | 2 cm length | 6 months | Consistent tension key |
Remember, every user’s experience is different. Are you ready to see which device fits your routine best? Keep these facts in mind while you decide.
Safety and Side Effects
Trying something new for your body feels scary sometimes, right? You want to know it's safe before you start. Penimaster Pro and SizeGenetics use different ways to hold on, and that changes how safe and comfy they feel for you.
Penimaster Pro holds the tip of your penis with a special vacuum system. No tight straps or pinching. What does this mean for you? You get less skin pain and can wear it longer without hurting. Many men say it feels gentle and doesn’t slip off easily. Doctors often choose it for patients because fewer people report problems. Have you ever felt scared to try something new because it might hurt? Choosing a gentle option often helps.
SizeGenetics is different. It uses a band or strap to hold your penis in place. It feels strong and sturdy. Some people like that “held” feeling, but others notice the strap can press too much. Sometimes, men feel sore or see a red mark after wearing it. Some even say the area feels numb or tingles. If you use it the right way and pick the right strap, you’ll lower these problems, but you may still feel pressure, mainly if you wear it for a long time. Ever tried new shoes that needed time to break in? It’s a bit like that.
Safety matters most. When you use these tools just as the directions say, doctors say both are safe for healthy men. Some men do get mild hurt spots or skin redness, mainly with SizeGenetics if straps are too tight or the device is too heavy for them. Penimaster Pro, with its vacuum, gets fewer of these reports. But if you feel pain—or see anything strange—take the device off and ask your doctor.
Still, many men use these devices every day around the industry. They share stories about small aches at first but say these go away after a few days as they get used to it. Will you think it feels weird the first week? Maybe, but you’ll get to know your body better and learn what feels good and what doesn’t. Always listen to your body.
Here’s a simple table so you can compare:
Device | How it Holds | Any Pain? | Safety Notes |
---|---|---|---|
Penimaster Pro | Vacuum (no strap) | Very mild | Rare problems, gentle grip |
SizeGenetics | Band or strap | Mild to sore | Safe if you adjust it well |
Want fewer side effects? Be patient, go slow, and follow the guide. If anything feels off, it’s always smart to stop and ask for help.
When you try tools like these, you take charge of your health. Isn’t that what matters most?
