Never used a traction device myself, not any from the stores that is. But I think that from the reported experience here from other members, it is safe to say that their reviews and claims are far fetched.
But that doesn’t mean they don’t work. They are great as an ADS to keep the penis elongated after workout. That means that they give good length results when used diligently and combined with manual stretches. But it is ludicrous to expect girth gains from solely this. For girth you need to jelq primarily, and other advanced exercises. That is assuming you already finished the newbie routine.
