VED, injections and pills rarely work for those who have venous leaks like me or they just aren’t practical for spontaneous intimate engagements.
While I found a VED not worthwhile for sex, they definitely are useful for therapeutic purposes. They suck blood into your penile tissues, keeping oxygenation levels up. They pull blood into the penis much as a regular erection does, but independent of arterial inflow or venous leak. In short, they work to keep your penile tissues from shrinking or losing elasticity.
This has been known to work before implant and lately to work even after implant.
Since therapeutic use does not involve constriction rings (you keep the VED on for the entire therapy session - usually about 30 minutes twice a day), any vacuum device that can maintain a seal will do, even cheap sex shop models or homemade ones. A vacuum is a vacuum and a $20 device can be as effective as a $500 medical grade device.
