Reviews for Pos-T-Vac reflect both positive and negative opinions from purchasers of the vacuum therapy system for erectile dysfunction. More than half of the reviews on Amazon.com are favorable, with buyers noting that the therapy produces successful erectile function, is more effective than pills and is easy to use. Others point out negatives of the product, noting that, for them, it did not produce successful erectile function, that the tube is too small, and that it causes pain or discomfort.
As of November 2015, Walgreens.com features a smaller number of reviews that also vary, with slightly more than half of the reviews being favorable. Reviewers positively note that the product performs just as advertised and yields quick results with no after effects. Others complain of pain with use, missing parts and a high price point. The reviews also tend to be either strongly in favor or strongly opposed, with one Walgreens reviewer raving that it worked every time and another calling the product a torture device.
Additionally, Pos-T-Vac products receive overall positive reviews on VitalityMedical.com. Reviewers affirm that the company's products allow them to successfully maintain erections and perform sexually. Three reviewers specifically claim that the Pos-T-Vac pump aids the erectile dysfunction they experienced following prostate removal.
