Penimaster PRO – My Complete User Review & Package Comparison
If you’re serious about improving length, correcting curvature, or recovering after surgery, the Penimaster PRO is one of the few traction devices I can confidently recommend after months of personal use.
I’ve tested different extenders over the years, but this one stood out because of its vacuum adhesion technology, medical-grade build, and modular package system.
In this review, I’ll share my real impressions as a user, break down each package with pros and cons, compare them based on experience, and explain why I chose Penimaster PRO over competitors like SizeGenetics.
First Impressions – Unboxing & Build Quality
When my order arrived from the official Penimaster store, the first thing I noticed was the premium presentation. Everything was neatly packed in a sturdy case, with separate compartments for the chamber, diaphragms, rods, belts, and accessories.
The materials felt solid — no cheap plastic.
The chamber was soft where it needed to be and rigid where stability was important. As someone who’s had devices break on me before, this was a good start.
The Packages – What’s Inside & Who They’re For
One thing I like about Penimaster PRO is that you’re not locked into one system forever. You can start with the basics and upgrade later, or buy a complete set from day one.
1️⃣
Belt Expander
My Impression: This became my go-to for discreet daytime wear. I could work at my desk, go for walks, and nobody noticed.
Pros:
- Comfortable under clothing
- Multiple wearing positions (waist, leg, shoulder)
- Great for multitasking
Cons:
- Less precise tension control than rods
- Elastic will eventually need replacing
2️⃣ Rod Expander
My Impression: Perfect for home sessions where I wanted exact traction control. I could measure progress and slowly increase tension.
Pros:
- Precision traction adjustments
- Excellent for Peyronie’s correction
- Stable and reliable for long sessions
Cons:
- Less discreet, not ideal for moving around
- Requires a fixed position to wear
3️⃣ Weight Expander
My Impression: More of an advanced option. I used this after 3 months to target ligament stretching. The downward pull felt different from rod or belt methods.
Pros:
- Gravity-assisted stretch
- Good for advanced users
- Can be combined with other methods
Cons:
- Not beginner-friendly
- Requires careful form to avoid strain
4️⃣ Basic Package
My Impression: The most affordable way to start. I began here before upgrading. Same chamber quality, but limited without an attachment system.
Pros:
- Low entry cost
- Same medical-grade chamber
- Upgradable anytime
Cons:
- No traction system included
- You’ll likely want an upgrade soon
My 6-Month Routine & Results
I didn’t just test the device once or twice — I followed a real program.
-
Months 1–2: Belt system for 2–3 hrs/day, then 1–2 hrs rod in the evening.
-
Month 3: Increased belt to 4–5 hrs/day. Slight tension increase on rods.
-
Month 4: Added weight system twice a week, 20 min sessions.
-
Month 5: Measured +1.5 inches in stretched length, improved curvature.
-
Month 6: Final measurement — +2.1 inches and significant straightening (~25° correction).
What made the difference? Comfort. With older strap extenders, I couldn’t last more than 45 minutes without discomfort. With Penimaster PRO, I could wear it for hours without pain — meaning more total traction and faster results.
Technology & Medical Facts
The vacuum adhesion chamber uses negative pressure to hold the glans without cutting circulation. This:
- Prevents slippage
- Avoids nerve compression
- Allows longer safe wear times
Medical classification: Certified Class 1 medical device in the EU, used by urologists for post-surgical therapy and Peyronie’s disease.
Biological principle: Traction stimulates cell division (mitosis), creating new tissue over time.
Pros & Cons from My Experience
Pros:
- Unmatched comfort
- Multiple wearing options
- Proven medical basis
- Upgradeable system
- Durable, German-made quality
Cons:
- Not the cheapest option
- Learning curve for proper setup
- Weight system requires experience
Why I Chose It Over SizeGenetics
I also tested SizeGenetics. It’s a solid strap extender, but:
- Penimaster PRO’s vacuum grip was more comfortable
- I could wear it longer without skin irritation
- Having multiple systems (belt, rod, weight) kept my routine varied
If comfort and flexibility are priorities, Penimaster PRO wins. If you want a simpler, cheaper strap system, SizeGenetics can work — but expect shorter daily wear times.

Final Verdict
After 6 months, I can say the Penimaster PRO is not just another extender — it’s the most comfortable and versatile system I’ve used. The package flexibility, medical-grade build, and results make it worth the investment.
If you’re ready to commit to a program and want the best balance of comfort, technology, and results, this is the device to get.
