Hey ruff, the device I use is the euroextender. Basically I just use it to keep my wang from turtling, meaning when your wang marshmallows and gets real small. After I do my hanging or wet jelqing and I finished my warm down, I use it immediately after to prevent the turtling effect. This has helped alot with flaccid gains, and somewhat erect gains. So I would go ahead and give it a try
