Review on 🚲 TAC 9 Tube for Bicycles - 700c x 18-23, Presta Valve, 32, 48, 60 or 80mm Length - Choose Valve Size and Money-Saving Option in 1 Pack or 2 Pack by Erik Peterson

Terrible product. The quality is cheap, made in Taiwan. To prevent tire blowout, follow the instructions VERY CAREFULLY AND CAREFULLY. I was able to ride the bike once then when I checked the bike again the interior burned out. Place the 2nd inner tube GENTLE AND CAREFUL, making sure the tube is positioned correctly to avoid pinching - there were areas in the 2nd inner tube that swelled disproportionately to the others. I took the tire off and made sure the rubber had weak spots/zones that were causing uneven inflation throughout the tube. Save money and buy them at your local store.
