Review on 6-Piece Valve Extenders Tire Stem Extension Angle Wheel Adapter Set for Car Motorcycle Bike Truck - Silvery, with 3 Variations by Jason Graham

Maybe I should have tried them all but one was enough. Instead of making it easier to fill with air, it ended up leaking air, causing the tire to lose air. I tried tinkering and fumbling when I got tired of refueling, but this thing was useless. If I kept it in the perfect spot it wouldn't leak, but it's completely useless! I do not recommend this product. I think the tolerances are too loose and the quality isn't good or consistent. Of course it was cheap so I should have known better!
