Looks,no one has one, may colors,super easy to get the bolt out
I guess price?
it is true you get what you pay for. you could buy a neck off semi B.O.B for mabey $50 less but it well be more work, wont look as bice and be cheaper made. this body is super easy to put on theres even a vedio on techts website showing you how to. all you have to do to get the bolt out is to just unserw the back cap and your done! there is no leaks!! my fohen body would leak a lot..and there was no problems whit the fohen body they just leak a lot. But if you want a B.O.B body and want the BEST then get the techt sleeper ion body and plus Todd is a great guy and stands behind all his products and well help you whit all problems you might have.
