Its exactly the same as the sp adapter, which imo is a bad way of getting the alt 5v. Its basically a splicer that cuts into the 5v line going to the hd. The downside of this is that if you screw it up you can cause a short and possibly blow out your hd, or just severly damage the line itself. I didn't like when xodus thought of this and I don't like that xecuter is doing it.
