Our other recommendations
Following Sizegenetics, we have 3 other penis extenders that we believe will give you great results in the long run.
- X4 Labs extender is great value for your money. Starting at only $199.95 for the starter package and having exceptional Hybrid Traction System of comfort (combines both silicon comfort strap and classic "noose" strap), X4 Labs extender will give you great results. However, unlike Sizegenetics, X4 Labs doesn't have penis exercise program included with it, so you might need more time to achieve desired penis size gains than with Sizegenetics.
- FastSize is another good penis extender. Coming in 2 packages (Basic Package and Advanced Package), FastSize extender is another great option for safe & fast penis enlargement. Using FastSize, you can expect first visible size gains in 3 months minimum.
- ProExtender is a 4-part penis enlargement system. It consists of penis enlargement device, penis exercise program ("For Men only"), 1 bottle of penis enlargement pills (VigRX) and 1 bottle of sperm increase pills (Semenax).
Keep in mind that FastSize and ProExtender don't have any special comfort mechanism to it, so it might be a bit uncomfortable in the beginning when wearing those penis extenders.
