Review on 🏎️ Mission Automotive 2 Pack Premium Replacement: Superior Performance and Durability by Jack Ford

Need one, it's good that there are two packages. The first tube installed held air for about two weeks and ran at 30psi on a lawn wagon. Then flattened. I was hoping the patch was all I needed, but I found that the valve skirt (the rubber ring that holds the valve to the tube body) was somewhat loose and was leaking air. I have no way of solving this problem and can only assume that the welding process was not sufficient. I've replaced it with a second tube and see if the problem comes back. I really haven't inspected any of the pipes that carefully. These are internal tubes, they hold air or they don't. Added two stars for excellent customer service only. The seller contacted me directly shortly after I posted the initial two star review and arranged a full refund. I call that great. Thanks seller!
