Vacuum erection devices (VEDs) are commonly recommended by urologists to treat erectile dysfunction. We explored consumer views on VED use through a qualitative analysis of 1,500 Amazon.com reviews for 21 of the most popular VED products. Reviews were analyzed using GPT-4, identifying common themes and subthemes. Electric and manual VEDs were compared, and a multivariable ordinal regression was built to identify factors linked to higher product ratings. The most common themes were efficacy (1,375/1,500, 92%) and user experience (82%). Electric VEDs compared to manual devices had more frequently mentions of ease of use (46% vs. 34%) and better design features (26% vs. 17%). A 5/5 rating was linked to fewer mentions of deficiencies, malfunctions, warnings, and desired changes compared to 1/5 rating. Each 1 USD increase was linked to an average 0.10-point drop in ratings (95% CI: -0.12 to -0.08). Compared to non-electric, non-sex toy products, those with electric features and additional sex toy functions had average rating increases of 0.72 points (95% CI: 0.44 to 1.00) and 0.40 points (95% CI: 0.13 to 0.67), respectively. Amazon reviews generally show positive sentiment towards VEDs, with electric models favored for ease of use, though patient education is essential for safe use.
