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 ($327, get 15% OFF)
My Impression: The Belt Extender was the most comfortable option for long daily wear and felt very natural during movement. I liked using it while working or walking because the vacuum system reduced pressure and made longer sessions easier.
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
Order the Belt Expander with 15% OFF if you want the most comfortable option for long daily wear, multitasking, discreet use under clothing, and an easier beginner-friendly traction routine.
2️⃣ Rod Expander ($366, get 15% OFF)
My Impression: The Rod Extender provided stronger and more direct traction compared to the belt system. It took some time to adjust correctly, but the stretching felt very consistent once I built a routine.
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
Order the Rod Expander with 15% OFF if you want stronger and more precise traction, structured stretching sessions, better tension control, and a system often preferred for Peyronie’s correction routines.
3️⃣ Weight Expander ($396, get 15% OFF)
My Impression: The Weight Extender felt more advanced and delivered a deeper pulling sensation during sessions. I would only recommend it after adapting to regular traction because the intensity is noticeably stronger.
Pros:
- Gravity-assisted stretch
- Good for advanced users
- Can be combined with other methods
Cons:
- Not beginner-friendly
- Requires careful form to avoid strain
Order the Weight Expander with 15% OFF if you already have traction experience and want a more advanced stretching method with stronger hanging tension and deeper pull intensity.
4️⃣ Complete Set ($409, get 15% OFF)
My Impression: The Complete Set gave me the best overall experience because it combines multiple traction methods in one system. I liked being able to switch between rods, belt, and hanging depending on comfort, intensity, and daily routine.
Pros:
- Most versatile package available
- Includes multiple stretching methods
- Best long-term value
Cons:
- More expensive upfront
- Requires time to learn each method
Order the Complete Set with 15% OFF if you want the most complete PeniMaster PRO experience with multiple traction methods, maximum flexibility, and the best long-term value without needing future upgrades.
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).
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:

Allows longer safe wear times
Prevents slippage

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.
