Review on Revolutionary Colby Valve Permanent Stem Replacement - Effortless Installation from Outside the Wheel! by Brett Morrison

I never write reviews but this product was so perfect I had to. The valve stem was dry and leaking. I couldn't move the tire to the side far enough to replace the valve stem with a stock one. I pulled out the old one. Added this one. Tightened and inflated the tire in 2 minutes. All without dismantling the wheel. I drive two days. PERFECT! Many Thanks.
