#7 Rated Penis Extender: Male Edge
PeniMaster PRO has long positioned itself as a premium penis traction device, targeting men seeking non-surgical solutions for penis enlargement and curvature correction. German-engineered and marketed with medical credibility, the device uses a vacuum adhesion system combined with rod or belt traction options. While the company touts innovation and medical validation, our in-depth evaluation—based on user testimonials, device specifications, and industry benchmarks—yields a moderate score of 61 out of 100. This review breaks down why.
What is PeniMaster PRO?
PeniMaster PRO is a vacuum-based penis extender that uses a chamber to suction the glans (head) of the penis into place, eliminating the noose or strap system common in older devices. It can be used with either a belt system (which loops around the waist or shoulder) or a traditional rod system to apply traction. This hybrid approach is meant to offer users more flexibility and comfort in their routines.
The device is intended for use in penis lengthening, girth development, and Peyronie’s disease (penile curvature). It has been promoted for both medical and cosmetic uses and is CE-certified in Europe.
Our Ratings for PeniMaster PRO
Performance and Results
PeniMaster PRO performs adequately in its primary mission of providing steady traction to the penis. Clinical backing does exist, particularly for its use in treating Peyronie’s disease and post-operative penile rehabilitation. However, while it may offer some incremental gains in length over several months of use, the performance is not overwhelmingly superior to competitors.
Many users report needing to commit to daily wear of 4-6 hours for several months to see results of 0.5″ to 1.0″. Gains beyond this threshold are uncommon. Users looking for aggressive results or who are already experienced with other devices often find the traction levels lower than expected. Some also experience difficulty maintaining suction beyond a few hours due to loss of vacuum seal.
Comfort and Wearability
This is where PeniMaster PRO scores higher. The vacuum adhesion system reduces the discomfort associated with compression-style noose extenders. It provides better circulation and minimizes the risk of discoloration, pressure bruising, or nerve impingement.
However, the tradeoff is that the vacuum system requires a significant learning curve. Correct setup involves multiple parts, including diaphragm membranes, sluice rings, and lubricant. Improper setup leads to loss of suction or painful blistering. For uncircumcised users, achieving a consistent seal can be frustrating.
The weight of the rod system also limits mobility, and while the belt system is more discreet, it may still bulge under clothing.
Value and Cost Considerations
PeniMaster PRO is one of the most expensive extenders on the market. Kits range from $321 to $409 USD, depending on configuration. Additional accessories (extra diaphragms, sluice rings, lubricant, etc.) add ongoing costs. Replacement parts are not cheap.
Given that other extenders (such as Quick Extender Pro or SizeGenetics) offer similar or superior performance at lower price points, PeniMaster PRO struggles to justify its price unless you specifically need its vacuum-based comfort or medical certification.
Warranty and Guarantee
The product comes with a 5-year warranty and a 30-day money-back guarantee, which is competitive. However, some users report slow response times and difficulty getting replacements approved. The return process is not as streamlined as it should be for a premium product.
Privacy Factor
Shipping is discreet, with plain packaging and no indication of contents. This is a strength. However, the actual use of the device, especially the rod version, is not discrete—you’ll need private space and likely to remain stationary while wearing it.
Customer Service
This is one of the biggest weaknesses reported across forums and user reviews. Customers complain about unresponsive emails, poor support documentation, and delays in shipping and returns. There are also language barrier issues when dealing with the German headquarters. For a premium-priced product, this is unacceptable and severely impacts its rating.

Final Thoughts
PeniMaster PRO is a technically innovative device with a good reputation in the medical field and a niche appeal among users needing high comfort or Peyronie’s correction. But for the average user seeking affordable, effective penile enhancement, it falls short in too many areas to justify the price.
It scores points for comfort and design, but underwhelms in value, customer service, and ease of use. With a final score of 61/100, we can only recommend PeniMaster PRO to users who specifically require its vacuum glans chamber or who are willing to pay extra for potential medical certification and modular configuration. Everyone else would be better served by one of the top performers in the field.
