Are you talking nutted axles or skewers?
If nutted, getting the tension right is just a matter of walking the wheel back as per good ol' Sheldon Brown. Easy and safe and, I would suggest, safer than relying on yet another gadget in there to go wrong.
If skewers, well, I'm learning not to like them very much (actually, it's more a case of all my misconceptions being confirmed).
