After installation, the tube/tire is leaking air at a rate =/> than 5psi per 1 hour.
Begin by completely removing the TyreWiz body and TyreWiz valve extender from the presta valve. Clean any excess grease/dirt/grime from the presta valve and TyreWiz valve extender. Re-install the TyreWiz following the Installation Video, making sure to apply a light amount of grease to the TyreWiz valve extender threads.
If the tube/tire is still leaking air, please get in touch with our customer service team here.
