Has anyone tried refunding their PeniMaster?

Supposedly you can get a full refund in the first 30 days and they even pay for shipping. Is this true or do they have some hidden requirements?

Its expensive as hell, and im not sure if it would work for me as im uncut, but if their claim is true, what could i loose by trying it?

I just want an extender i can put on and forget about while im wearing it :(
