We’re here to support you if you have any questions. That's the Wilson Amplifiers difference.

Second 100% Guarantee: Anytime during your 2-year manufacturer's warranty (1 year for refurbished/renewed), should your unit not perform to its usual standards, contact us, and we'll take care of it. We're not here for the one-time sale. We're here for the lifetime supporter. We want to be loved.
