⭐⭐⭐⭐⭐ Emily R. - Breast Cancer Survivor
"I was nervous about how I’d feel in clothes after my mastectomy, but these silicone forms have truly restored my confidence. The triangle shape fits perfectly in my everyday bras—no shifting or discomfort. I can wear fitted dresses again without worrying about symmetry. The material feels so natural against my skin, and I appreciate that it’s medical-grade and hypoallergenic. I’ve had mine for five months now, and they still look and feel like new."Purchase Date: August 2024 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Jessica M. - Yoga Instructor
"As someone who’s always on the move, I needed a prosthesis that could keep up. The Advanced Model with dual ventilation ports has been a game-changer. I wear it during hot yoga classes, and even with intense sweating, there’s no irritation thanks to the breathable design. It stays securely in place under my sports bras, and the 20% lighter weight compared to my old foam insert makes a huge difference. I wish I’d found this sooner!"Purchase Date: February 2025 | Usage Period: 3 months
⭐⭐⭐⭐☆ Daniel K. - Lingerie Consultant (purchased for client)
"I recommended the Base Model to a client recovering from surgery, and she’s been thrilled. The discreet triangle design works beautifully with both plunge and full-cup bras. She especially loves how it doesn’t create bulk under thin fabrics. It’s not fully customizable like a 3D-molded option, but for the price point, it’s an excellent entry-level choice. We’re now considering upgrading to the Pro Model for long-term use."Purchase Date: November 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Dr. Laura Bennett - Oncology Nurse Practitioner
"We’ve started recommending these forms at our cancer care center, and patient feedback has been overwhelmingly positive. The Pro Model’s moldable silicone is ideal for post-surgical patients with irregular chest contours. The central ventilation port significantly reduces skin irritation, which is a major concern during recovery. Plus, knowing it’s FDA-approved gives both patients and clinicians peace of mind."Purchase Date: January 2025 | Usage Period: 6 months

"I’ve tried several prosthetics over the past two years, and this is the first one that truly mimics the weight and drape of natural tissue. The 500g balance feels perfect under blazers and evening gowns. The triangle shape is genius—it fills the bra just right without spilling over. As someone who works in fashion, I notice every detail, and this passes every test."

"I wear mine from morning school drop-off to evening errands, and I forget I’m even wearing it. The ventilation opening makes a noticeable difference—I don’t get that sticky, sweaty feeling I used to with my foam insert. Easy to clean, too. Highly recommend for anyone needing all-day comfort."

"Bought the Base Model for my partner after her surgery. Simple to use, lightweight, and blends well under clothing. Only reason I didn’t give 5 stars is that we had to try two sizes before finding the right fit. A sizing guide would be helpful for first-time users."

"After fitting hundreds of post-mastectomy patients, I can say the Triangle Silicone Breast Form line stands out for its balance of comfort, aesthetics, and functionality. The concave design is ideal for seamless integration into standard and mastectomy bras. For active patients, I recommend the Advanced Model; for those with complex contours, the Pro Model’s full moldability is unmatched in its price range."
Dr. Alan Reyes - Rehabilitation Specialist
"Prosthetic weight and symmetry play a crucial role in posture and shoulder alignment post-surgery. At 500g with balanced distribution, this form helps prevent muscular imbalances. The lightweight design reduces strain, making it suitable for long-term wear during rehabilitation and beyond."
