ProExtender and SizeGenetics both aim to help with length, girth, and straightness. You wear each device on your body for hours every day. Both use traction, which means a gentle stretch over time.

Effectiveness and Results
Picking between ProExtender and SizeGenetics? Most want to know what really works. You probably wonder—what sort of changes could you see with each one? Here’s what current research and real stories say.
Claimed Benefits
ProExtender can add size over a few months. Some claim up to 2 inches in 90 days with daily use. People use extra pills like Vigrx or Semenax (Official & Safe ✅) with it, hoping to boost results. SizeGenetics works on gentle pulling too. It uses special pressure settings to make the process smoother. Many find a steady gain in both size and strength after a few weeks.
Both choose safe, non-surgery ways to help. ProExtender’s benefits include better confidence and stronger feelings. SizeGenetics stands out for its use in fixing bends in the penis, called Peyronie’s disease. Its design is made to fit better than simpler extenders. That means you feel less pinching during wear.
User Experiences and Testimonials
What’s it like using these at home? Lots of men have tried both. With ProExtender, some are happy with the gains. A few say it feels flimsy, and they wish it fit better. Do you ever stop using something that feels odd? That’s common here.
For SizeGenetics, you see more stories about comfort. People talk about noticeable growth in a few weeks. Some find it heavy or pricey, but others like all the ways they can adjust it. Imagine wanting to wear something for hours—would comfort change your choice?
With both, regular use matters. The more you wear each, the better your odds, based on stories and trial data. But for most, how you feel using it—safe, comfy, or not—may say more than just numbers. Want changes that last? Many say sticking with it gives the best chance.
Safety and Potential Side Effects
You want to know if ProExtender and SizeGenetics are safe, right? Let’s look at how they affect you and what small side effects could show up.
Both ProExtender and SizeGenetics use gentle pulling to help you feel more confident. If you use them as shown in the guides, you don’t need to worry about surgeries. Many men say they only feel a little sore at first, like after trying a new stretch at the gym. Think about when you start a new exercise—sometimes your muscles feel a bit tired or tight. Does that sound familiar?
ProExtender is easy to use but needs careful hands. When you use ProExtender, you may feel minor soreness or see some redness, especially when it’s new for you. One man shared that after his first week, his skin turned a bit pink. He slowed down, listened to his body, and took a break. The swelling went away, and he felt ready to try again. Did you ever put on a shoe that didn’t fit right and then had to loosen it? It’s almost the same.
SizeGenetics works gently but feels a bit heavier when worn a long time. If you keep it on too long, your body can feel tired or strained. One person said he wore it for hours to see fast results but ended up feeling sore. He learned that small steps work best. Soreness, redness, and device slipping often stop if you pause, adjust the fit, and go slower the next day.
Both tools don’t use needles or cutting. So, risks from surgery, like infections, are not a worry. If you follow the steps and increase the stretch little by little, you’ll lower the odds of pain. When your body sends you signals—redness, pain, or swelling—it helps to listen and make small changes. Have you ever pushed too hard and had to slow down?
Here’s a quick look at what some men notice:
Device | Common Feeling | How to Help |
---|---|---|
ProExtender | Soreness, redness | Take breaks, ease tension |
SizeGenetics | Tiredness, slip | Adjust fit, shorten time |
Want comfort? Slow and steady wins. Want safety? Keep an eye on how you feel, go at your pace, and adjust when you need. That way, you get better results and an easier time. Isn’t it smart to let your body guide you?
Pricing and Value for Money
How much do you want to spend on a device? Price often shapes your pick between ProExtender and SizeGenetics.
ProExtender costs less in most stores. You get a simple frame, a soft band, and foam for comfort. Some bundles come with extras like VigRx or Semenax pills. These pills promise to help with performance, but the real value depends on your needs. The frame feels light in your hand but might not hold up well over years. Many choose ProExtender for a low starting cost, especially if you want to try a traction device for the first time.
SizeGenetics asks more from your wallet. Why does it cost more? The frame uses strong metal, and you can adjust the tension very carefully. Some sets also include a moisturizer and multivitamins, but these extras don’t have much proof behind them. When you open the box, you notice it feels strong and smooth. Many people keep using SizeGenetics because it fits well and can take daily wear without breaking.
Let's look at their main offers and prices in this table:
Device | Typical Price Range | Core Features | Extras (in some packages) |
---|---|---|---|
ProExtender | Lower | Silicone noose, foam padding, simple rods | VigRx, Semenax pills |
SizeGenetics | Higher | Stainless steel, fine-tune tension, multiple rods | Moisturizer, Boost multivitamin |
Think about what matters to you. Do you want a tough device that lasts and lets you adjust a lot? Or do you want to spend less and get some extras, even if it’s not as sturdy? If cost drives your choice, ProExtender wins. If you want comfort and long-term use, SizeGenetics stands out.
Which sounds right for you? When you set your budget and list your needs, your answer often becomes clear.

Customer Support and Warranty
You want help when you buy something new, right? ProExtender gives you simple, clear instructions in the box. Some people like how quick it is to set up. But there isn’t much info about calling or emailing for help, so you might need to figure out some things on your own. Ever needed an answer fast and couldn’t get it? That gets frustrating.
SizeGenetics stands out for its support team. You get a team ready to answer questions and guide you if you get stuck. Many users say it helps them feel confident while learning how to use all the parts. Some SizeGenetics packages also include extras, like creams and vitamins. If you like having lots of support, this brand fits better.
Do you ever wonder how long your device will last? ProExtender keeps it basic—warranty info isn’t easy to find. Some folks wish they had more details if something breaks. SizeGenetics offers a more robust guarantee and tells you directly if your product is covered. When something goes wrong, having that warranty brings peace of mind.
Choosing between them? Think about how much help you may need and if warranty coverage matters to you. Some users like fixing things themselves. Others want to pick up the phone or send an email and get fast answers. Both styles work—you know what you like best.
Conclusion
Choosing between ProExtender and SizeGenetics comes down to your priorities and comfort. If you want a straightforward device with a lower price tag, ProExtender might fit your needs. If you value advanced comfort settings and strong support, SizeGenetics offers those benefits.
Take your time to weigh what matters most—cost, comfort, effectiveness, and support. Whichever device you pick, consistent use and patience are key to seeing real results. Always listen to your body and adjust as needed to stay safe and comfortable on your journey.
